Hi Sweets :
antiVIRUS program(s) are NOT that good with resolving trojan and/or worm problems;
I hope you have MORE than an antivirus program for security on your computer !?
At a minimum should have 2 antiSPYWARE/antiTROJAN programs to "deal" with the
trojans, worms, etc and I recommend you start with "SUPERantispyware" from http://www.superantispyware.com
; I have its "FREE" version . Another recommendation
would be AVG antispyware ( formerly known as "Ewido" ) available from : http://www.ewido.net/en/
AND I hope you are using a 3rd party firewall rather than that 1-way one that comes
with XP SP2 !?
You MAY need to "empty" your AVG antiVIRUS "vault" just prior to running the
"Full System" Scans of the antiSPYWARE/antiTROJAN program(s) to have them
effectively "dealt" with !? I am unsure on this point .
