Over the summer I got infested by the Sir Cam worm. After a few days, I got it off my computer and everything seemed fine. But now in the past two months or so I find that I have all these weird programs suddenly on my computer. They don't seem to do anything, just slow the thing down, most of them just crash and usually it leads to my computer stalling when I try doing a simple task like opening a file or playing a cd or a dvd. I've done multiple scans of my system with Norton Anti-Virus and it says that there are no viruses on my computer. I thought I could live with the occasional re-boot, but it's getting to be really annoying. I'm pretty sure my current problems have nothing to do with my earlier problems in the summer. So here is my question: If I uninstalled windows and then re-installed it, would all of these little programs that are crashing all the time go away? Any help would be greatly appreciated.
