Apparently my computer is infected. I'm not sure how or when this happened. Today Norton's 2010 was complaining about this Backdoor.Tidserve.I!inf , saying that a file SI3132.sys in the windows/system32/drivers/ folder was infected, on the K drive. The K drive is not actually in use, in fact it didn't have a drive letter assigned because I only backed up the partition yesterday, with Partition Wizard. So I think this infection might be on my primary C: drive and Norton 2010 didn't pick up on it until it scanned the COPY of my system on the other drive. (I hope that made sense, right?)
I deleted the SI3132.sys file off the K drive so Norton's thinks the risk is resolved but when I rebooted (disconnected the K drive before I did that), Norton 2010 didn't load at all and when I tried to click on the program to bring it up, nothing would happen. There was the a little "pop" sound, which is the sound my computer makes when it's stopping a popup. Apparently it's stopping Norton's from loading, now.
I rebooted in Safe Mode and running a full system scan but I'm not real optimistic because Safemode showed that the SI3132.sys file is loaded even in Safe Mode. So if it is infected... well, we'll see if Norton's notices this but so far it's scanned over 1 million files and hasn't found anything. I do have a lot of files.
From what I've been reading, Norton 2010 cannot remove this Backdoor.Tidserve.I!inf , if that's what the problem is.
