About a day ago, Sophos antivirus (school supplied antivirus) said it detected a trojan (specifically Virtu-gen). It immediately prompted me to run a Trojan Hunt scan which I did. A specific .dll file from my system32 file kept coming up in the scan as belonging to Virtu-gen, but I could not find a file by that name and do not have its exact name anymore (pedawne or something similar). Sophos flashed this alert about 14 times. At the end of the scan, I was told to reboot and that no action could be taken until reboot.
During the scan, my unupdated Windows Defender (also school supplied, unupdated because I have tenuous internet at home and am on break) ran a scan of my system with no results.
I manually rebooted through the shutdown/restart as opposed to Sophos button at the end scan. I did not see if anything strange happened during startup as I had gone off to brush my teeth. When I came back, by system had become unusably slow. I have just gotten sophos to even open in the last few minutes about 30 minutes after startup. Task manager is unusable as it takes a long time for me to be able to click on anything. I managed to get to the processes tab, but when I try to scroll down or click on an application, it tries to refresh the window and gets nowhere. CPU usage reads as 100% but none of the processes I can see in the window without scrolling are the culprit, though Tea Timer is using 1 percent.
I read the Sophos guide on how to resolve this issue and am unable to implement it as my computer is still unable to access quarantine or initiate a scan. The links an buttons in the Sophos window are unresponsive. I have more or less determined that I am completely unable to run applications due to this slowdown.
The little flashing light that usually activates when the CPU is working is not flashing at all, even when task manager thinks I am using 100% of my CPU.
In attempting to resolve this issue after the catastrophic reboot, I tried rebooting in safemode through the F8 method but startup freezes up when I do this. I get as far as a screen full of file names from the system32 file when they stop scrolling and the system becomes unresponsive.
I am using the internet from a library computer at this point.
I have tried rebooting the system several times in safe or normal mode, restoring last known good settings, allowing scan disk to run from hard resets and not letting it run after hard resets to no avail.
I am running Windows XP Media edition on an Acer Aspire 5600 with 1.6 GHz Core Duo Processor, 1.5 GB RAM, and two 50 GB hardrives (so I figure if worst comes to worse I can salvage one).
I do not THINK I have boot disks for windows XP, so I am not sure if I can reformat my system if needed. If there are other options to do that, I would still be willing.
It may take some time for me to respond to any advice since, as stated above, I am using a library computer at the moment, and my time online is limited. Thanks for your time.
