I have a laptop that had a Internet Security 2011 Virus in it. I removed the viruses with Malwarebytes and Super AntiSpyware. The problem is that when I load the computer back into windows, it can't open any program at all. When I try to open a problem like Internet Explorer, It tells me what program should I open it with. This is with all the programs in my computer, even Windows System Restore. I tried running in Safe Mode because I heard that you can still run some programs in Safe Mode, but I can't. I am not sure how to repair this kind of problem.
Computer is a Lenovo Laptop and running windows XP Home
