problem came from a trojan called scvhsot.exe (note that the spelling is not the same as svchost that is more common in the system, I think?). That person said that the trojan named scvhsot.exe was stored in the system folder, and was identified by scanning using kaspersky antivirus software. (I guess you could just search for it without using that software. But maybe they were pointing out that the software identified it as a virus.) So, if you find that file, then that person said: Delete the exe file, restart the computer, then open the autorun.inf files of each drive you have and empty it. In the file you can see it opens sss.exe, which is the program that (they presume) is causing all the exceptions. When you delete scvhsot, this sss.exe also gets deleted. Once you empty the autorun.inf files of all your drives and save them, restart again. It should work (they say). They went on to say: If you want to search for the autorun.inf files, you can use "Ava find Professional" searcher. Make sure you change the file's read/write permissions to let you delete its contents and save.
