ALL ABOUT COMPUTER VIRUSES


In this article, i will try to dwell on computer viruses; one of the problems that will
make you regret you purchased a laptop computer. Though it is very complex dealing with
viruses, they are not as difficult to prevent or curb as they are made to look like. I know
some people have decided not to buy a PC because of the trouble those around them go through in
trying to stay on top of their computer viruses. Fortunately, you are here at LAPTOPLEMANA to
learn and arm yourself against computer viruses.

WHAT THEN IS A COMPUTER VIRUS?

A computer virus is a small software program that spreads from one computer to another
computer and that interferes with computer operation. A computer virus may corrupt or
delete data on a computer, or even delete everything on the hard disk.

Computer viruses are most easily spread by attachments in e-mail messages or by instant
messaging messages. Therefore, you must never open an e-mail attachment unless you know
who sent the message or unless you are expecting the e-mail attachment from someone you trust.
because computer viruses can be disguised as attachments of funny images, greeting cards, or audio and video files.
Computer viruses also spread by using downloads on the Internet and this is the commonest
way to catch a virus.
