Hi, I am having a problem with Windows Vista Home edition and I think it's a virus. The problem started a few weeks ago - everything was running sort of slow and random programs would shut down. Also, this website would pop up in Explorer saying my computer was infected with a trojan. I ran virus programs, it'd find a few infected items and remove them and then things would be fine for a days.
So, yesterday, everything got really slow & started shutting down again. I ran the virus program and it said nothing was infected. I restarted my computer and when it came back up, nothing. Just a black screen (though sometimes it'll show my cursor).
So, I played around with it last night and finally tried to go to the last known good configuration. It took FOREVER to sign in, but it finally took me to my desktop. But the whole time I was there, it wouldn't let me open any programs and when it did, they'd freeze up or not respond. Also, I kept getting alerts about security threats. I left it on overnight but it went to my sign-in screen and it wouldn't let me sign in. I restarted and I'm back to the black screen.
Is this a virus? How can I get rid of it? Do I need to reinstall Vista? I am prepared to do that if necessary (I'll be losing some things, but I've gotten over it) but just wanted to make sure that will help. Thanks!
