After stupidly opening an exe in an email, I got infected by Trojan.W32.Beagle, which disabled my AV (avast!), and prevented it being installed. I ran the AVG antirootkit and it found this I then used combofix to remove the malware, and it removed everything except - C:\WINDOWS\System32\Drivers\aghslwes.SYS After rebooting, I reinstalled avast! and ran a boot scan which it passed, however, eveytime i run AVG antirootkit, it comes up with an infected file like 'aghslwes.SYS' - and if I clean it and then reboot, there will be another file there with a different name. eg: C:\WINDOWS\System32\Drivers\ancmq6f7.SYS Does anyone know how to get rid of this? Thanks ps: I realise that a drive image would have solved all my problems, but I hadn't gotten round to it yet, and deleting the partition and formatting then reinstalling the OS (XP pro) and software would take days.
