I started a thread a little earlier which I thought was resolved click here
So, I have 2 SATA drives and a back up IDE drive. The SATA drives have been written back to zero and no viruses were detected. I installed XP, installeed AVG before I installed my modem and connected to the internet. Evrything seemed to be running smoothly but now evrytime I copnnect I get a virus (a Trojan Horse) in the Windows system. AVG is able to heal it but this means a restart and it seems to just get infected and then another and then another. The computer basically slows to a halt and I have no idea how this can be happening. I have never had trouble with viruses before - it is only since I installed these new drives. Any advice?
Download Ewido Anti-Malware trial version click here
When installing, under 'Additional Options' untick 'Install background guard' and 'Install scan via context menu'.
Launch Ewido by double clicking the icon on your desktop. The program will now go to the main screen. You will need to update Ewido to the latest definition files. On the left hand side of the main screen click update then click on Start Update.
Then select 'Settings'. Under the bottom section 'What to Scan?' make sure 'Scan every file' is ticked. Select 'OK' and you will return to scanning options. Click on Complete System Scan and the scan will begin. This scan can take quite a while to run.
While the scan is in progress, you will be prompted to clean the first infected file it finds. Choose 'Clean' (or 'Delete' if 'Clean' is not an option). Then put a tick next to 'Perform action on all infections'. Doing this enables the scan to proceed automatically until its completion. Click OK.
Ok, installed and ran EWido, which found 46 infected objects, which is way more than AVG found. I don't mind paying, but I used Norton for a while and hated it and then moved to AVG and it just happened to be free. Am I better paying for a service such as NOD32 or Ewido? Mostly though why all of a sudden am I inundated with viruses? I'm gonna put SP2 on and then I may try thr Restore thing suggested by johnnyrocker. Totally-brained you said unlikely to be the drives, so it is possible?
I believe it is possible if you just format but rereading what you said you've written to every part of the hard drive, I can see no way that anything could survive that. The reason I asked about SP2 was. When I built my new PC at Xmas I went online with antivirus installed before I installed the SP2 update and AVG kept flagging up a backdoor virus, this happened everytime I went online. Since I reinstalled SP2 its gone, so one part of SP2 is obviously the patch to close the vunerability that allows this virus in.
