Everytime I want to save Word/Excel/Powerpoint file on my email, it hangs there. If I leave the PC for 2 hours it will still be like that after I came back. And everytime I surf the net and try to open the same kind of file,it will not open. So frustating. My friends have to print screen the word file so that I can save it. It's not like this before. I'm afraid it's because my PC was infected by some viruses and I deleted some infected files that maybe have cause this problem. How to solve?? Thank u.
