A computer virus is a type of malware that, once it has infected a computer, can propagate itself to other computers on the network. Viruses can be spread through a variety of means, including email attachments, infected files, or Trojans.
Once a computer is infected with a virus, it can be difficult to get rid of. The virus may disable antivirus software, prevent the computer from starting up, or delete files. In some cases, the virus may be so destructive that the only solution is to reformat the hard drive and reinstall the operating system.
There are a number of ways to protect your computer from viruses. The most important is to keep your antivirus software up-to-date and to be careful about what files you open and attachments you download. You should also be careful about where you visit on the internet, and never click on links or download files from unfamiliar websites.
What to do if my PC have a virus?
If your computer has been infected by a virus, the first thing you should do is disconnect it from the internet. This will help prevent the virus from spreading to other computers.

What are the causes of computer virus?
Computer viruses are a very real and ever-growing threat to the security of our digital world. They can cause immense damage to both individuals and businesses, and can be very difficult to get rid of. So, what are the causes of computer virus?
One of the main causes of computer virus is simply human carelessness. People often inadvertently download viruses onto their computer when they open emails from unknown senders, click on links in dodgy emails, or download infected files.

Finally, computer viruses can also be spread through network vulnerabilities. These are weaknesses in a computer’s security that allow viruses and other forms of malware to enter the system.
So, these are some of the main causes of computer virus. However, it is important to note that there are many other ways in which viruses can be spread, and that the risk of infection is always increasing. Therefore, it is essential to take steps to protect your computer from viruses and other forms of malware.
