A virus can cause your computer to crash, or it can delete files and prevent you from being able to access certain websites.

Fortunately, there are some easy ways to protect your computer from these threats. Be sure to install a good antivirus program and keep it up to date. Avoid downloading files from untrustworthy websites and only open email attachments from people you know and trust. When browsing the web, be cautious of clicking on links, even if they look legitimate. If you think a website might be suspicious, don’t hesitate to run a quick Google search to check for reviews or warnings.

How to protect your pc from viruses?
There are many ways to protect your pc from viruses, but the most important thing you can do is to install a good antivirus program and keep it up to date. There are many free and paid antivirus programs available, so choose one that you are comfortable with and that fits your needs.
In addition to installing an antivirus program, you should also be sure to keep your operating system and other software up to date. Many viruses exploit security vulnerabilities in outdated software, so it is important to keep everything up to date. You can typically set your software to update automatically, or you can check for updates manually on a regular basis.
Another way to protect your pc from viruses is to be careful about what you download and open. Many viruses are spread through email attachments or infected websites. If you are unsure about a file or website, it is best not to open it. You can also use a tool like VirusTotal (https://www.virustotal.com/) to scan files before downloading them.
Finally, you should create backups of your important files on a regular basis. This way, if your pc does become infected with a virus, you will be able to restore your data from the backup.
How to remove a virus from your pc?
If you think your pc has a virus, there are a few things you can do to remove it. First, try running a virus scan with your antivirus software. If that doesn’t work, you can try using a malware removal tool. Finally, if all else fails, you can reinstall your operating system.
In conclusion, there are a few simple steps you can take to protect your PC from viruses. By installing an antivirus program, keeping your operating system and software up to date, and avoiding suspicious emails and websites, you can significantly reduce the risk of infecting your computer with a virus. However, no matter how careful you are, sometimes viruses can still slip through the cracks. That’s why it’s also important to have a backup plan in place so that you can recover your data if your PC does get infected.
