The trojan Win32:Kolweb-N (Trf) keeps appearing on my computer... how do I get rid of it?

I scan with Avast Anti-virus, Spybot, and Spyhunter. Avast always finds the trojan and supposedly fixes the problem... but it keeps coming back. Every time I restart the computer I get a warning about it. It does this even when I restart the computer without even going on any websites, so I know I'm not getting it from any sites, Is it just hanging around? Is something else making it come back? Please help... I've had to restore my computer TWICE in the last two months because of trojans. All of my security settings are on 'high', so I don't know why I keep getting these things!

Try the following

Turn off SYSTEM RESTORE

Run Spybot AND Adaware (links below)

Run a FULL AV Scan too

Only once system is clean and the trojan does NOT return do you re enable system restore.

Also make sure you have DELETEED the files from the Avast chest.

I'd reccomend these 2, run each in turn

ADAWARE fro www.lavasoftusa.com (Free personal version)

also SPYBOT S%26D from www.spybot.org (Again free for home use)

Also worth having in toolbox is CCLEANER from www.ccleaner.com again a free download, and a good general windows tidyup utility.
