How to Avoid Computer Viruses

Computer viruses are pieces of code, which infect a user's PC in order to gain access or damage the system. Any computer connected to the Internet is susceptible to a computer virus; PC is more common than Mac. In most cases, a virus is used to gain access to the user's computer in order to gain control, but can also be used to steal information. Viruses are mostly problematic because they are self-perpetuating and can email themselves out through the PCs e-mail service without the user being aware of it thereby infecting anyone in the user's contact list.

There are many ways for a computer to become infected by a virus. The first is opening e-mails, the second of which is downloading files from the Internet.
