What is Computer VirusWhat is a Computer Virus?A computer virus is a malicious code designed to spread from host to host by itself without the user’s knowledge to perform malicious actions. It imposes harm to a computer by corrupting system files, destroying data or otherwise by being a nuisance. The reason for designing a computer virus is to attack vulnerable systems to gain admin control and steal confidential information — Cybercriminals prey on online users by tricking them.

In other words, a virus spreads while the user is viewing an infected advertisement, visiting an infected website, opening the attachment in the email, or clicking on an executable file. Besides that, connecting with an already infected removable storage device such as a USB drive also spreads the infection.

Therefore, it is essential to install robust antivirus software on a computer to steer clear of all such threats.

This is because the polymorphic viruses alters its signature pattern whenever it replicates. Overwrite Virus – This type of virus deletes all the files that it infects.
