Question

I am having a problem in copying and transferring my files within my
computer. Whenever I try to copy something, I get an error like FILE
INTEGRITY VIOLATED...I dont know what is it. I formatted my computer
once. I am facing the problem since then. And I use a Vista genuine
basic. Please help me to solve this. I also deleted many files due to
this as I thought their might be some virus, but still no results.
