I scanned my computer with both Spybot S&D and AD-Aware recently.

Each time I ran a scan, Spybot detected Bifrose.LA and Fake.Wget. Ad-Aware detected W32.TrojanDownloader.Agent.AM.
It looked like they were part of the same malware.

Now, Spybot doesn't detect Bifrose.LA nor Fake.Wget (it took a few scans to remove them). However, Ad-Aware still detects W32.TrojanDownloader.Agent.AM and I know (because I searched on the Internet) that it is part of the same malware as Bifrose.

Please help me!

P.S.: I just downloaded "Trojan.Bifrose Removal Tool" from http://www.winternal.org/modules.php?name=Downloads&d_op=viewdownload&cid=9
I don't know this program, nor if it is trustworthy, but this is its scan log (some of the detected files might be false positive):

none of the online scanners seems to work :scratch:
however,i think i solved my problem: trojan.bifrose didn't reappear this morning
yesterday, i spent the day running different anti-spyware and antivirus scans, and i think that they removed it completely

well, thanks anyway
