What is a computer virus?
Think of a biological virus – the kind that makes you sick. It’s persistently nasty, keeps you from functioning normally, and often requires something powerful to get rid of it. A computer virus is very similar. Designed to replicate relentlessly, computer viruses infect your programs and files, alter the way your computer operates or stop it from working altogether.
In 2013, the botnet virus Gameover ZueS was discovered to use peer-to-peer downloading sites to distribute ransomware and commit banking fraud. While tens of thousands of computer viruses still roam the internet, they have diversified their methods and are now joined by a number of malware variants like worms, Trojans, and ransomware.
How does a computer virus find me?
Even if you’re careful, you can pick up computer viruses through normal Web activities like:
Sharing music, files, or photos with other users
Visiting an infected website
Opening spam email or an email attachment
Downloading free games, toolbars, media players and other system utilities
Installing mainstream software applications without thoroughly reading license agreements
What does a computer virus do?
Some computer viruses are programmed to harm your computer by damaging programs, deleting files, or reformatting the hard drive. Others simply replicate themselves or flood a network with traffic, making it impossible to perform any internet activity. Even less harmful computer viruses can significantly disrupt your system’s performance, sapping computer memory and causing frequent computer crashes.
