Trojan.Swizzor: NFected by NVidia’s 197.75 update??
Personal story here…
A couple nights ago I tried to watch a movie on my Windows 7 PC, which for some reason wasn’t liking it. At one point it spit up a window that said that it could be a driver problem and that I might want to update my drivers.
For graphics I have an NVidia 8600GT running driver version 126.96.36.19907, which so far has worked flawlessly. But I thought I’d check out NVidia’s site anyway. It turns out that they do have an updated driver package so I download it and rather than save it first I choose to run it directly. As soon as the install package started Bitdefender popped up, stating that a trojan was prevented from running.
“Huh?”, I thought, as I had just scanned it fully about two days prior and it had been found clean. So I try again…same thing. The actual virus was trojan.swizzor.gen.8 and it had about 30 infections which freaked me out. I did a little searching which at the time didn’t show much. So I ran Bitdefender’s antivirus and about 3 passes later it shows as clean.
A few days later the Bitdefender boards have lit up by others having similar problems, some having shown the infection after trying to install the NVidia package. However, it could be a false positive. I’m not willing to try to reinstall the driver update right now, but we’ll see what happens.
UPDATE 3/5/10: Now I’m getting BSOD’s from some sort of a driver issue. So I don’t know if the old driver became corrupt or if something else is now broken. Hooray.
UPDATE 3/6/10: I saw today that there’s been overheating problems with NVidia’s 197.75 update package and they’re recommending a rollback to the prior driver, 197.21. So I downloaded and ran 197.21 without issue. No BSOD’s or virus popups as of yet. So it seems that 197.75 should be avoided irregardless.
FINAL UPDATE 5/4/10: I’ve upgraded the drivers again to the latest version. I still have occasional blue screens but no more virus problems. I’m guessing it was a false positive.
