I have 2 problems. One is the problem list below:
"http://www.symantec.com/security_response/writeup.jsp?docid=2006-101910-1040-99" and the second one is:

"From: <serv (AT) selectplans (DOT) com>
To: <bgsbd (AT) bellsouth (DOT) net>
Subject: Mail server report.

Mail server report.

Our firewall determined the e-mails containing worm copies are being sent
from your computer.

Nowadays it happens from many computers, because this is a new virus type
(Network Worms).


Using the new bug in the Windows, these viruses infect the computer
unnoticeably.
After the penetrating into the computer the virus harvests all the e-mail
addresses and sends the copies of itself to these e-mail
addresses

Please install updates for worm elimination and your computer restoring.

Best regards,
Customers support service"

This last one says to install KB2515-x86.exe. I am not sure what I should do.
