This area of the window displays the current list of worms, viruses, and
trojans. No selection actions are required.
How Does this Affect Me?
A virus is a program that infects other programs and files and can spread when
a user opens a program or file containing the virus. A virus needs a host (the
program or file) to spread. A worm is a program that can also perform
malicious acts (such as delete files and send email); however, it replicates
itself—it does not need a host (program or file) to spread. Frequently, worms
are used to install a backdoor (a way for an attacker to gain access without
having to login). A trojan horse is a stand-alone program that is not what it
seems. For example, it may seem to be calendar program, but when you open
it, it erases all your files and displays a message, such as "Ha ha, I deleted your
files!" Trojan horse programs do not spread or replicate themselves.
What Do I Need to Do?
Make sure you are running an anti-virus software program, and that it is kept
up-to-date.
