A
virus is a malicious piece of code designed to wreak havoc on the computer that
activates it
The most common source of
viruses today is the internet and more specifically email
Often they come cleverly
disguised as a joke or special gift
As a rule you shouldn’t open
emails if you don’t know who they’re from
The problem now is that some
viruses actually attach to your address book then send themselves out to
everyone in it.
So it is possible for a
friend or colleague to unknowingly forward the virus on to you.
The only sure way to prevent
this kind of activity is with some good
up-to-date antivirus
software.
The better quality ones
offer an online update service to ensure
the very latest virus definitions are available.
Companies like Symantec also
post fixes for the more common viruses on their web site
along with manual removal
