About three weeks ago, my roommate popped a DVD into our computer. An automatic prompt asked him to download a certain DVD viewer to our computer, even though we already have one (!?!?!) He did, the computer went "screwy," so he uninstalled the program. He's even less technologically minded than I am, so honestly, that's the best description I have of what happened. Anyway, our computer immediately slowed down. I had to turn our firewall off to even access the internet. Windows XP is running extremely slow as well, taking a full minute to open any program. Our internet access has slowed to a crawl (we have broadband), even without a firewall. At first, it was something that I said I'd just deal with later, until I realized that I can't even listen to music while reading my email - all the songs skip because the computer's working too hard??? I've run our anti-virus numerous times, run Ad-aware, etc etc, and nothing seems to help. I am so frustrated! So, a site suggested that I make a HijackThis log, but what do I do with it now? Can anyone give some advice?
