I'm in desperate need of help with my vista. I'ts home premium, almost 90% sure it is. Anyways, I was on the comp about a week ago and I accidently clicked on an ad or something and it started a download so I stopped it about mid-way through when I noticed it. A few days later I turned my comp on and at the desktop the toobar at the bottom was like, POSSIBLE MALWARE DECTECTED. Then I was like oh s**t. So I quickly turned my comp off THINKING it was a good idea. But about two days ago, about a week after my last comp use I tried turning my comp on and I put in my password to login to my comp and what do ya' know? It's a black screen, then a message, WINDOWS EXPLORER HAS STOPPED WORKING. And it just gives me the option to cancel the message. Basically alls I can do is hit Control-Alt-Delete and shut the comp down. To be honest, I'm REALLY lucky it didn't effect my wireless router cause I just typed ALL of this fron my DSi so someone, ANYONE help me! I don't even care if I have to clear everything from my comp I just want it to turn on! Thank You for your time.
