I have read the other posts but don't see where you provide any solution or advice. Maybe I'm just missing it but all I see are questions very similar mine which really does not help.
How did this virus get thru Avast in the first place?
Why does it keep recurring on EVERY re-boot even without being connected to any network?
An Avast Scan after deleting the Trojan-Gen infected files runs clean.
I don't know what the Trend, RAV, KAV, spybot and ad-aware scannners are. I have SpyKiller and NoAdWare and the both now run clean.
I am running Avast 4.1 Pro Build 4.1.357 on Windows XP Pro with all MS patches current.
