Help -- Norton periodically tells me that my PC is infected with download.trojan virus & can't remove it. I have cleaned with both AdAware and Spybot. I have also run Norton AV in safe mode and it does not detect it. I have also deleted temporary internet files. Any other suggestions? I am still bombarded with pop-ups, even when using Google pop-up blocker.

Have you flushed out the restore folder? The virus will get backed up in this folder (if Win 2000 has a restore folder), though I don't know if it can get out.... See if there is anything here you have not thought of...... http://www.computing.net/security/wwwboard/forum/9036.html Response Number 4 Norton should find it (if it's updated). A neighbours PC had this a few weeks ago. While in safe mode, look for a file winfavourites.exe I think this is the actual virus.

You may find that this thread answers your question...*S* http://www.computing.net/security/wwwboard/forum/9167.html

as for the popups they may be unrelated, try getting a firewall http://www.grisoft.com/us/us_dwnl_free.php this ones for free and works well

Thanks for the feedback. As far as I can tell, Win2K doesn't have a restore folder, so that's not the problem. And, Norton is updated, but doesn't find the virus in safe mode. I've now installed a firewall, and maybe this will help a bit. Nevertheless, I know that the virus is still lurking out there. Given that Norton DOES periodically detect download.trojan virus 'on the fly' (though not when doing a full system scan from safe mode) I'm confident that the barrage of pop-ups are related to the virus. Amazingly, they seem to largely bypass the firewall and several simultaneously-active pop-up blockers (one from earthlink and one from google). Any other suggestions?

Hello, You can try this excellent program called Trojan Remover 6.19 this program is a 30 days trial freeware, but fully updated with recents trojan's signatures.... Read well the "readme" files of the program to be able to use correctly the two embaded scans of the program: one to check your memory RAM, second one to hunt, detect and eradicate the worm hidden somewhere in your hard drive....

Well, it looks like ZoneAlarm will take care of things. Even if the virus is still lurking somewhere, as long as I keep the firewall on, NO MORE POP-UPS! Thanks for all your suggestions.
