Hi everyone!
My home edition avast 4.7 version found a new trojan on my Hdd but was unable to clean it or send it to the chest.
the Trojan detected was in the protected and hidden c:/windows/installer folder.
The name reported by avast is “Binary.WiseCustomCalla26” in th folder 30227.msi
I currently run Ad-adware, Spybot search& Destroy, Windows XP pro SP2 complete firewall and hardware DEP.
Here is how I got rid of the bug;
Used install disk to boot to recovery console. Logged in as admin. CD to C:\windows\installer.
Entered password for access for installer folder. Deleted \30227.msi\ directory. exited and rebooted back to my normal desktop. Ran avast again (thorough) and it no longer sees the trojan.
My SCSI HDD drives do not access constantly anymore and the system no longer freezes and shutsdown normally.
Thought this might help others in this situation.
