lFor the last couple days I have had problems with windows police pro virus which i was able to fix. Now Protection System virus is attacking me. First it wouldnt let me open any programs, but finally I was able to download and run IObit security 360 which found a large number of threats. It did not really solve the problem though, instead now for just about every program (except microsoft office, and a couple others) it says "Choose a prgram to open this file", basically nothing will run. Also Protection System virus is still there and is doing it's usual thing. I can't use the internet or open regedit, and I have no idea how to fix this. My OS is Windows XP.
