What is a computer virus?
A computer virus is a type of malware that infects a computer system, mobile device, or other electronic device and can replicate itself to other systems. The most common types of viruses are boot sector viruses, file attachment viruses, and malicious code. Boot sector viruses infect the master boot record (MBR) of the hard drive and affect only operating systems that use MBR. File attachment viruses attach themselves to executable files and spread through removable media such as USB drives. Malicious code attacks random files or folders on your computer system and attempts to install a form of ransomware known as ransomware.
What’s the difference between malware/viruses?
Malware is a term used to describe any software that can harm your computer or personal data. If a website you visit is not trustworthy, there’s a chance that it could be infected with malware. If you’re trying to download an app or game, there’s also the possibility that it could contain malware.
A virus is a piece of software that takes control of your computer and causes havoc. It’s usually installed by clicking on an infected link in an email message or through social media like Facebook Messenger. Many viruses use file names to disguise themselves from detection by antivirus programs and other security software, but they don’t always work as intended. Viruses are often hard to remove because they replicate themselves and try to spread further on their own; different types of antivirus software may have different ways of detecting them.
Why should you use a VPN, and how does it helps protect against the virus?
The main reason why you should use a VPN is to protect your privacy. When you connect to the Internet, your IP address can be tracked and used to determine your location. This process is known as geolocation. The more websites that access your data, the easier it is for them to find your location. A good VPN service will encrypt all of the traffic between your computer and the server, so they can’t see what websites or services you visit.
A good VPN service also masks your IP address and makes it appear like you’re connecting from another country. This makes it harder for hackers who try to steal information by accessing unprotected networks on the Internet. Therefore, using a VPN is one of the best ways to protect yourself against viruses and malware on the web.

The benefits and risks for the users
The benefits of a VPN are manifold, and they include:
- Security:A VPN encrypts all your data, which is sent through an encrypted tunnel, and the only person who can see it is the VPN server. This way, your data is safe from prying eyes, especially government agencies or hackers who want to steal your information or even monitor your internet usage.
- Privacy:You can get rid of ads, trackers, and other malicious software that you may install on your device by using a VPN. This allows you to surf the web without being tracked.
- Speed:With a fast VPN service, you can get faster download speeds than with standard connections because all traffic goes through the encrypted tunnel.
There are many risks of using a VPN, including:
- Unencrypted traffic —The VPN server might not be secure and could be used by hackers or interceptors.
- DNS leaks —If you use a public Wi-Fi network that a hacker has compromised, they can get your DNS information. This information is sent to the VPN server and can reveal your true location.
- Man-in-the-middle attacks —A hacker waiting for your data could intercept it and send it to another party.
- Spamming —Spammers will try to trick you into clicking on malicious links with fake ads pointing to their servers.
