Hi all,

My internet suddenly became extremely slow a couple days ago, and I ran an avast! antivirus and Ad-Aware scan to see if there was anything there. Ad-Aware reported Win32.Backdoor.SDBot on the machine, and then removed it. The problem was that the next time the computer was started, the malware was back again. Avast! reports no problems whatsoever. Both are up to date.

So far I have:
-Attempted to run Spybot, but after its installation several programs on my machine refused to run, so it was removed via system restore when a normal uninstall failed to fix the problem
-Cleaned out temporary files as in the prep guide
-Scanned with Ad-Aware, which seems to remove the file until the next reboot but does not fix it altogether
-Scanned with BitDefender, which reported and deleted other viruses but not this one
-Run McAfee Stinger, which reported no problem

The computer is running avast! antivirus, Ad-Aware, ZoneAlarm, and the ZoneAlarm ForceField beta (the beta was installed after the malware attack) as protection.

Is this very sneaky malware or is Ad-Aware reporting a false positive? Any help would be very much appreciated! The HijackThis log attached was created first thing after the computer was rebooted, before Ad-Aware removed the malware again. Thanks in advance.

Hi Claudius, Welcome to the forum,

We are sorry for the delay in responding. The volunteers here are swamped and unfortunately not all logs get answered as quickly as we'd like. If you still require help please post a new HijackThis log into this topic and I'd be happy to assist.

Thanks

Andy
