Hi list, hope this is relevant; not completely sure, but it is all about virus
software and has links to free stuff in it. Sorry if it's a red herring.
Cheers

Worms and Trojans - What's The Difference?
Windows - all versions
A worm is a program similar to a virus. It is considered by some to be a
variant or subset of a virus in that it makes copies of itself but does so
without needing to modify a host. Like viruses, worms may (or may not) do
things other than replicate. They can act as Trojans, viruses, and cause
computer damage as well. Their function may be nothing more than sending itself
to as many addresses as it can harvest from the computer that it infects. Worms
are generally distributed by email as attachments or via peer-to-peer file
sharing programs. A worm can be polymorphic, which means that it assumes a
different appearance each time it hits an inbox. Some worms with many different
faces can have the same basic programming. Solution? Install a good anti-virus
program and keep it updated! We recommend AVAST. The free version is excellent
and will keep you protected -you can get it free here. (The free version is for
home/personal use only.)
Trojan horse programs are named for the giant wooden horse that concealed
Greek soldiers who used it to invade the ancient city of Troy. Like that famous
trick, a Trojan horse program conceals hidden programming. The hidden function
may just be a joke, or something malicious. Vandals often use Trojan horse
programs to destroy or steal other people's data, Normally a Trojan will be
programmed to send information from the infected computer to another computer
or Web server. Trojans can be concealed inside other software or distributed
via email as attachments. Having a good software firewall installed can prevent
sensitive data from being sent by the Trojan. So install a good firewall
software program and leave it turned on. Also, many good anti-spyware programs
(like Spyware Doctor ) now detect and remove Trojans.
A word about email attachments: Some people will click on any e-mailed
file that they receive. Programmers with nothing else to do but get their kicks
by writing malicious programs; and vandals who are out to steal personal
information have seized this opportunity, They've created programs designed to
spread to all those who correspond with careless users. Because of this threat,
the only 100 percent safe e-mail file attachment is a deleted e-mail file
attachment.
Protect yourself! Install a firewall. Make sure you use a good anti-virus
program and keep it updated at least twice a week. Scan your computer online at
least once per week just to be doubly sure you're computer is not infected.
Another important piece of advice we urge you to follow to protect your system
from infection is to keep your Microsoft Windows Updates current. Be careful
with email attachments! Never open them directly from email. The best policy is
to immediately delete them, but if you think it might be from someone you know,
and want to make sure it's safe, save it to your desktop and scan it with your
anti-virus program or use the online scanning service (free) above. Another
good piece of advice - Install a good anti-spyware program like Spyware Doctor
and keep it updated frequently. Scan your computer for spyware at least twice a
week or set your anti-spyware program to scan your computer automatically a
couple times a week while you sleep. Make sure you know what's running behind
the scenes on your computer. Don't assume you're safe because you've not
installed anything new - you can become infected easily these days without even
knowing it.
