Certain programs on my computer have been slowing down considerably in the last few weeks. For instance today my explorer.exe was very slow. And I discovered that for some reason I have five copies of explorer in my windows directory. Explorer, explorer(2), explorer(3), and so on. So I deleted the extra ones and now it works fine. I've also had this happen for iTunes, and AIM, and a few others. Anyone know what's copying these programs and how I can get it to stop?
