Antivirus: An antivirus is a program that detects and removes malicious software from a device, such as viruses, Trojans, worms, and spyware. Antiviruses work by scanning the system for suspicious files and comparing them to a database of known malware signatures. If the antivirus finds a match, it will alert the user and take action to remove the malware.

VPN: A VPN (Virtual Private Network) is a virtual private network that connects devices and networks over the Internet. VPNs encrypt Internet traffic, hiding user activity from the prying eyes of hackers and governments. Furthermore, VPNs allow users to access geographically restricted resources such as streaming services that are only available in certain countries.

So what is the virus?

A virus is any unwanted program that enters a user's system without their knowledge. It can self-replicate and spread. It performs unwanted and malicious actions that end up affecting the System performance and user data/files. A computer virus can be thought of as a computer disease, just like human viruses that cause disease in humans.

And the antivirus?

An antivirus software, as the name implies, is a program that works against a virus. It detects or recognizes the virus and after detecting the presence of the virus, works to remove it from the computer system. Antivirus software works as a prophylactic, so that it not only eliminates a virus, but also prevents potential viruses from infecting your computer in the future.

Antiviruses have evolved over the years to offer more features and protection. Some of the common resources include:

• Firewall: Protects the device from network attacks.
• Real-time protection: Continuously monitors the system for suspicious activity.
• Phishing Protection: Blocks malicious websites that try to steal personal information.
• Mobile device protection: Protects smartphones and tablets from malware.

Antiviruses are not perfect and may fail to detect malware that is not in their database. Additionally, they can interfere with device performance, especially on older computers or those with fewer features. However, even with their limitations, antiviruses are still a fundamental piece of cybersecurity.

Why do you need antivirus software?

A system without antivirus is like a house with an open door. An open, unsecured door will attract all intruders and burglars to your home. Likewise, an unprotected computer ends up inviting all viruses into the system. An antivirus will act as a closed door with a security guard for your computer, preventing all malicious invading viruses. So will you leave your door open to trespassers?

What damage can a virus do to your computer?

If your computer is attacked by a virus, it can affect you in the following ways:

• Performance reduction
• Damage or delete files
• Format hard drive
• Cause frequent computer crashes
• Data loss
• Inability to perform any task

The number of advantages that using an antivirus provides is countless. Some of the most important are:

• Protection against viruses and their transmission: An antivirus software mainly performs a prophylactic function. It detects any potential viruses and works to remove them. Remember that all this is done primarily before the virus harms the system. So this means that most viruses are fought before they do damage to your systems. An antivirus can fight many viruses in a single day without your knowledge. Avast and Norton are some of the most popular antivirus software available on the market today. If a virus has attacked your system, you can transfer it to your friends, family and networks. So, if you want to protect your computer system and your acquaintances' computers, consider getting an antivirus.
• Block spam and ads: If you do a quick research on how viruses enter their victims' computer systems, you'll be amazed at the proportion of viruses that use pop-up ads and websites to enter computers. Pop-up ads and spam sites are one of the most common gateways used by viruses to infect your computer and damage your files. Software like Bullguard Internet Security works against these malicious websites and ads that contain viruses, blocking direct access to your computer network.
• Defense against hackers and data thieves: Hackers often use a malware or virus program to access a victim's computer. They install malware on the computer without the victim's knowledge. Hackers send malicious emails to victims. Then the hacker can easily hack the desired files and programs. After that, they can use victim's data as per their will; they can delete or damage it and steal it to demand ransom later. Anti-malware such as Malwarebytes will place an anti-attack block or run regular scans to detect the presence of any hacker or hacker-based programs on the computer network. Therefore, antivirus software provides complete protection from hackers.
• Ensures protection against removable devices: Think about the times you've transferred data to and from your computer using removable devices such as USBs. Countless, right? You may have experienced a computer slowdown or crash after plugging in a friend's USB. Ever wondered why this happened? This is because the USB or removable device served as a transmission device for a virus. So should you stop using removable devices because you never know which USB might have a virus? No! Just get antivirus software that will scan all removable devices for potential viruses to ensure no viruses are transferred.
• Protects your data and files: Antivirus software keeps an eye on every file that enters your system. All these files are put in a scan to check for any quirks or maliciousness. Viruses can easily be transmitted to your network through infected files and in turn can potentially harm your data and files. You may even suffer complete loss of your precious data at the hands of such viruses. One Avira software solution ensures that your data and files are adequately protected.
• Improves PC performance: Think of two computers side by side. One of them is suffering the consequences of a virus attack, such as slow processing speed and frequent crashes. The other is antivirus protected. Which one will have a better speed? The one with antivirus, for sure. This is because the computer has no problems because the antivirus has stopped the virus before it can do any real damage. Some antiviruses can even delete and remove junk files from unknown sources to free up disk space, increasing PC speed.
• Firewall protection against spyware and phishing attacks: A firewall typically monitors traffic in and out of your computer network. When coupled with antivirus, firewall protection double-checks every file or data you send or transfer from your computer via the Internet to another network. The same goes for files and data that you receive from an external network. You could unintentionally open a malicious website or email and then fall victim to a phishing attack. A phishing attack occurs when attackers specifically target your login credentials, credit card information or any other personal information/data. This attack could result in substantial financial loss or personal leaks. Two-way firewall protection against antivirus software like Avast blocks and removes those emails or files that can harm you in this way.
• Limit access to websites to improve web protection: Accessing unauthorized websites can expose your computer system to various cyber threats including spyware, hackers, ransomware, etc. These threats can potentially risk your data and files. Antivirus software limits your web access to restrict your activities on unauthorized networks. This is done to ensure that you only access websites that are safe and harmless to your computer system.
• Keeping an eye on the kids: The biggest headache for parents in these advanced times is that their kids can openly access anything using the Internet, be it good or bad. Parents can't always keep an eye on what their kids are doing on the computer. And they can't educate their kids about the good and bad web all the time because they get irritated so easily. Antivirus software can be the solution for such worried parents. It can provide you with a monitoring tool through which you can keep track of your children's activities safely and efficiently. Antivirus software provides adequate records of your child's activities. ESET is one of the most important antivirus that offers parental controls.
• Protect your password: You protect your valuable data and accounts with a password and think that your data and accounts are protected. But what if someone steals your passwords using a virus? The password stealer can later blackmail you for ransom or use your password to access sensitive information. In addition to using antivirus, you might also consider using a password manager to improve security.
• Value for money: Most antivirus software is very affordable. Monthly or yearly packages offered by antivirus manufacturing companies are inexpensive. If you consider the variety of services that come with the premium antivirus package, you will surely think that the cost they are offering is much less. Also, if you're on a budget and don't want to spend money buying the premium version of antivirus, you can get free antivirus.

Is your computer better off without Norton antivirus ?

A virus attack can cause as much damage as forcing you to buy a new computer because the old computer was damaged beyond repair. Not having a protection mechanism for the computer system is like inviting viruses to the computer by providing clear and accessible entry.

Do you want to damage your computer with your own hands? If not, get antivirus software as soon as possible so that you can use your computer without the constant fear of falling victim to a virus attack.

What is Spyware?

Spyware is software that collects data from your device without your knowledge or against your will. Once you collect that information, you can send it to someone, somewhere, who will use it in ways that are harmful to you. These harmful uses can be relatively benign, like forcing unwanted ads on your screen or secretly tracking where you go online. Or they can be devastating, like emptying your bank accounts or blocking all data on your organization's servers until you pay a ransom. In other words, spyware is not something you want on any of your devices.

Anti-Spyware Coupon

Common Types of Spyware

Spyware generally falls into one of the four categories below:

• Adware: Secretly installed software that forces ads onto your device
• Trojans: Spyware that installs malicious software or steals information
• Tracking cookies: record your online activities and share them on websites
• System Monitors: Records everything you do and sends the information to potential crooks

That was a quick explanation. Now, let's look at each of these types of spyware in more detail.

Adware

Adware is a type of spyware that gathers information about the websites you visit online and the files you download. The purpose is to use this information to display advertisements which you will click on, thus earning commissions from the adware publisher.

These ads may appear in addition to or in place of ads you would otherwise see. Adware can slow down your system. It can also make your system unstable as the adware struggles with your web browser or operating system to force its ads on your screen. Adware also harms legitimate advertisers who can lose sales to the sneaky spyware publisher.

Trojans

Spyware Trojan is software that pretends to be something it is not. A Trojan may look like a video player or something similar, but it can actually steal information from your device and send it to the spyware company.

Some Trojans allow the spyware controller to gain partial control over your device. They can do things like read or delete your files. Sometimes they can encrypt your files and demand payment in exchange for decrypting them. This last nasty type of Trojan is known as ransomware.

A timely example of ransomware is the ongoing war between the city of Baltimore and someone who managed to get RobbinHood ransomware onto the city's servers.

Tracking cookies

Cookies installed on your device by a website can serve many purposes. Many of these services are beneficial to you, such as remembering your login information or the page you last visited.

Tracking cookies are a little different. Their job is to record your online activities so that marketers can more effectively target you with ads or other marketing materials.

Top advertisers can have their ads on thousands of websites. Whenever you visit one, the site may place a tracking cookie on your device. Over time, the advertiser uses these cookies to see where you are going and builds an increasingly detailed profile of your online activities.

They haven't done anything directly malicious, but most of us object to the number of companies that silently track us as we go about our lives online.

System monitors

System monitors are a type of spyware that can monitor and record virtually anything you do on your device. Typically, it can record keystrokes, chats, text messages, the websites you visit, the files you download, pretty much anything. Some of these apps can even capture screenshots of your activities to send to whoever controls the spyware.

Mobile Spyware

These malicious applications are in their own category because they have different limitations and modes of attack than spyware that targets regular computers. Some spyware can enter your mobile devices through SMS or MMS messages.

This type of spyware can be particularly ugly. Think about it. Your smartphone knows where you are at all times. It has built-in cameras and microphones, as well as tons of your most personal information. Now imagine a Trojan or System Monitor getting control of your phone. Talk about a personal privacy disaster. Ask Jeff Bezos, CEO of Amazon, what can happen to your life when someone gets their paws on the information that lives on your smartphone.

Apps that know too much

Many people consider installing apps on their smartphones that request data beyond what is necessary to do their job, regardless of whether they are approved to appear on an official app store. It is necessary to be careful!

How Spyware Gets On Your Devices

Okay, we agree that spyware is a clear and present danger to your privacy. But how does spyware get onto your computers, smartphones and other devices? We will see.

Probably the most common way for spyware to position itself to do its dirty work is through installation by another program. When you download and install software from a shallow source on the Internet, there's a good chance that software will secretly install some adware along with what you thought you were installing. Spyware creators will pay software developers to secretly install their junk on your device.

Another way for spyware to get onto devices is through security holes. These flaws could be in the security of your device. Researchers are constantly looking and finding ways hackers can bypass device security. If the crooks find one of these before it's patched, they can use it to put spyware on your device without your knowledge.

The other security flaws are human. Some people are so eager to get back to what they were doing on their device that they click on random popups without even reading them, just to make them disappear. Some spyware takes advantage of this to bypass your device's security. After all, you clicked the OK button, so you must install this dodgy-looking program.

A similar human error comes into play when opening emails or downloading files sent to you from unknown sources. This is a combination of human and device errors. You opened it and your device failed to recognize it as something bad. So let security pass.

Additionally, as we discussed in a previous section, a mobile device can be vulnerable to attack through the SMS or MMS messaging systems of the telephone system.

How to Tell If Your Device is Infected with Spyware

Finding out if your device is infected with spyware is not a simple task. After all, these things are hidden in the device in order to spy on it, so the developers will not make it easy for you to find them. Still, spyware often leaves telltale signs of its presence.

You might have a spyware problem if your computer has these symptoms:

• Your device is slow or crashes unexpectedly.
• Your device is running out of hard disk space.
• You get popups when you are online or offline.

Other signs that could indicate a spyware infection can include:

• Sudden problems with your Internet connection
• Your firewall or antivirus software for to work
• New icons appear on screen
• You suddenly find yourself redirected to another search engine

How to Know for Sure If You Have a Spyware Problem

While these are all good clues that you have a problem, the best way to know for sure is to run an anti-malware application to test your system for known spyware.

If the antispyware application detects spyware, it will probably offer to delete or neutralize it. That's great, but even though the app can do this for you, you should still follow steps 3 and 4 in the next section. The infection may be gone, but you still need to undo the damage it may have done.

In addition to a specialized program, many antivirus programs these days have built-in or optional antispyware features. This is particularly important if you have Linux boxes in your device collection to protect - there is no free anti-spyware for Linux..

What to do if your device is infected

If one of your devices is infected with spyware, you have a project ahead of you. The steps you need to follow are:

Step 1: Install Anti-Spyware

Step 2: Delete Malware from Your Device

Step 3: Change all your passwords

Step 4: Notify all financial institutions and other sensitive organizations of the issue

It is essential to perform these steps in this order. In particular, you don't want to change passwords until your device is clean. Do things in the opposite order, and the spyware might just pass your new passwords on to the bad guys while you're wiping them off your device.

How to prevent future infections

Whether you've just wiped a device or are looking to avoid the first infection, the steps to take are the same.

First, install the antimalware application of your choice. You want one that scans in real time, not just regularly scheduled scans. While regularly scheduled scans are better than nothing, imagine the damage spyware could do to your device and your life in the time between getting on your device and the next regularly scheduled scan.

Second, make sure your antimalware app is up to date and run a full scan of your device. Spyware could have landed on your device any time before the instant your anti-malware application started protecting it, so it's worth doing a thorough scan right now.

Third, make the following precautions part of your regular use of all your devices. Taking these precautions will significantly decrease the chances of spyware ever gaining access to your devices. So you don't have to worry about spyware getting past your device's defenses.

From now on, make sure:

• Have anti-malware software installed and running on all your devices.
• avoid download software from unofficial sources. While this is not a perfect guarantee of security, if you only download software from places like an official app store or a major publisher's website, it greatly reduces the chance of getting your device infected.
• Do not open an email from unknown persons. And do not open any files attached to these emails.
• Do not click on pop-up ads that suddenly start appearing on your device.
• Keep your anti-malware software, operating system (OS) and browser up to date. When a new spyware application starts to achieve its goals, you can install the patched version as soon as possible.
• Make sure browser extensions are up to date and look for options to enhance browser security. See this article on the best secure browsers for instructions on how to protect Firefox from attack.
• Enable your device's firewall (for devices that have them). A firewall can prevent suspicious apps from being installed on the device.

Completion

Spyware is an ever-present problem for any device connected to the Internet. In this article, we look at the various types of spyware, how it gets on your devices, how to recover from it, and finally, what you can do to prevent your devices from getting infected with spyware going forward.

Although the war against spyware continues indefinitely, if you follow the advice we give here, you will maximize your chances of avoiding spyware infections going forward.

But remember to always be vigilant, as malicious spyware often takes on new forms and is delivered by new methods.

What you need to know about using a VPN Norton

The internet has evolved over the years. We now have access to vast amounts of information and the ability to make connections is endless. Connecting to the Internet is easier than ever, however, users need to keep an eye on issues such as security and privacy. At work, we are using Internet tools to send and receive confidential information, purchase goods and services, and much more. In our personal lives, we are shopping and participating in massive social networks.

VPN discount coupon Norton

Each of these actions can leave us vulnerable. Identity theft, credit card fraud and many other crimes are committed by hackers every minute of the day. You may be wondering what steps you can take to better protect yourself when using the internet. A VPN can provide you with the necessary security and privacy you deserve.

What is a VPN Norton ?

Simply put, a VPN connects your PC, smartphone or tablet to another computer (called a server) and allows you to browse using that other computer's Internet connection (server). So if that server is in a different country, it will appear that you are in that country too, and that way you can access things you normally couldn't.

So how does this help you? Good question! Let's answer the following:

What are the benefits of using a VPN?

• Security: When using a VPN your data will be encrypted, which means that hackers will not be able to access it. If you're using a closed network for work, you can keep it completely private. This means security for you, your company and any sensitive material that comes into your possession. Encryption keeps you and your data safe. This is important for anyone who uses the Internet, but if you use it for business, it's even more important.
• Anonymity: If you want to browse websites in complete privacy, you must use a VPN. It acts as a mask to allow you to conduct your business anonymously on the internet. Unlike web proxies or IP masquerading software, a VPN will allow you to access websites and web applications undetected.
• Remote access to your network: Once you've set up your VPN, you can connect to it remotely from anywhere in the world with just an internet connection. You can securely log in to your network and access anything you want. For business, this will increase productivity. For users using a VPN for privacy, this means you won't need to send an email or attachment that can be intercepted. You can keep all your data on a closed network that only you have access to. And that access can be achieved anywhere.
• File sharing on your network: After setting up your VPN, you can share files with others. This means your network members will be able to easily access and transfer files to each other. This feature is increasingly attractive to companies that want to allow team members to securely access their work product. This is especially true for confidential information that you wouldn't want to end up in the wrong hands. A secure connection is the only way to share files without detection or interception.
• Avoid internet filters: In countries with more restrictive internet access like China, VPNs are extremely popular. In part, this is due to Internet filters that prevent native users from visiting social media accounts and spreading opinions critical of the Chinese government. This may seem like just a Chinese problem, but for people trying to do business with Chinese companies and individuals, it's a huge challenge. A VPN allows users in China to 'escape' the country's Internet policies and access a freer network. If you travel outside the country, you can use your VPN service to bypass that country's internet filters and behave on your own terms. For Americans, a VPN can allow you to access content such as regional social media platforms or videos that you might not have access to in the US. You may have encountered 'restricted content' or geographic restrictions that do not allow access. This will never happen again with a VPN. As our society becomes more global, this feature is indispensable.
• Changing IP Address and Server Location: You can change your IP address location or 'hide' your IP address/location. If you're connecting from Chicago but want to connect from a country in Europe, you can use a VPN to easily change your IP address to an address originating in Germany. It's simple. In addition, you will also be able to access regional content, websites and web apps that are generally reserved for internet users in Germany. Many companies in foreign countries do not have websites for each localized market. This means that you can access a German website at a .de address without being redirected to a .com address (if there is one).
• Better performance: Sometimes the available servers are not good. You may find that connecting via VPN can improve speed and performance when searching the Internet. It will certainly be better than a proxy network. VPN services are taking performance very seriously. In the past, VPNs could be slow, laggy, and you would constantly lose connections. New developments have made these inconveniences a thing of the past. And in many cases, using a VPN can result in better performance.

What are the differences between a free VPN and a paid VPN?

Weighing the pros and cons of using a free or paid VPN is pretty straightforward. In the previous paragraphs, you saw the advantages of using a paid VPN. Both paid and free VPN services aim to provide security, reliability, speed, customer support and anonymity. However, you may find that a free VPN is not living up to all these promises.

• Security: Many free VPNs use protocols that are not 100% secure. They use what is called a PPTP VPN, which has proven to be not the strictest when it comes to security. Paid VPNs allow you to use other protocols that help tunnel your connection more securely. A free VPN offers more security than not using a VPN. That doesn't mean you're getting the best security features out there. A paid VPN is the best way to get more security.
• Reliability: As you might have guessed, a free VPN is less reliable. Since you are using a free service, this usually means that the servers are not up to date and your resources are being stretched to the limit. If you plan on using a VPN to stay safe, you'll definitely want this service to be reliable and available at all times. Whenever there are connection failures (as can happen with an unreliable VPN), you are exposed to security risks. You need a stable connection that isn't dropped from one server or transferred to another. This not only results in a productivity slowdown, but also a potential security breach.
• Speed: We are all in a hurry. A paid VPN will allow you high speeds. You'll quickly connect to a remote server, be encrypted and anonymous in a matter of seconds. Connecting through a good VPN shouldn't be a headache and take forever. You don't want to wait to connect to the server. Most paid VPN services offer the fastest, most seamless way to get up and running. A free VPN can be unstable, and once you finally connect to a server, the connection can be slow and fiddly. If you are looking for fast and uninterrupted speed, a paid VPN can meet your demands.
• Customer Support: Good customer support is essential for any business. Whether the business is consumer-focused or business-to-business, you need to resolve issues quickly. Most free VPN services don't even have a customer support team. The prospect of not having a dedicated team to help you oversee your online security can seem daunting. This is even more true for users who want a VPN for their teams. A paid VPN will allow you to connect with professionals who can help you day or night. Not only will you feel secure and have peace of mind that you are being taken care of; a customer support team will also be able to help you resolve the more complex problems of using a VPN.
• Anonymity: One of the biggest attractions of using a VPN is being able to browse the web and conduct business anonymously. You don't want companies or the government to know everything you do online. It is a privacy and security issue. The only downside to using a paid VPN is the payment method. When you pay the VPN company, you also provide a billing address and other personal information. Now, most paid VPN services will guarantee that you are safe and that information will not be shared. For the most part, you should trust them. However, if anonymity is the goal, why would you disclose credit card and other personal information? Things are changing and many paid VPN services are allowing subscriptions to be paid for by cryptocurrencies and other forms of payment. Paying anonymously is an additional step. But for many people, it's not a big deal. Of course, a free VPN will give you a little more freedom. This freedom has a price, as you saw in the previous points.
• Number of Servers: Finally, another thing you should consider is the number of servers a VPN has in operation. Servers allow you to access the internet. They are what host you online. If a VPN doesn't have many servers, you won't be able to connect remotely in as many places (this affects anonymity and security). You should choose a VPN with a robust portfolio of servers in multiple locations around the world. Free VPN services will have a limited amount of servers because they are expensive. You will find most paid VPN services with many more servers all over the world. Keep an eye on this when choosing your VPN!

VPN and streaming services (Netflix, Amazon, etc.)

Services such as Netflix, Amazon Prime Video and HULU and several others place strict geographic restrictions on their content. For example, people residing outside the US do not have access to HULU. Why? Well, HULU is strictly a US service. The same goes for BBC iPlayer, which only works for UK residents.

Geo-restriction is one thing, but limiting a show or movie to a certain region is quite another. While the former is usually due to unavailability of service in a region, as in the case of HULU, the latter is a case of content licensing agreements. Netflix and Amazon Prime Video limit several shows to the United States only due to their licensing agreements.

Fortunately, you can bypass all these restrictions using a quality VPN streaming service. Major VPN providers can unblock all these sites with ease. These services implement their proprietary VPN features to give users the ability to seamlessly connect to their favorite streaming sites.
