I also noticed my computer wouldn't let me go to certain websites. It didn't make sense which ones were blocked. I couldn't access http://mail.yahoo.com for example (or any other email website.) I couldn't go to many spyware remover websites. A lot of google searches would not work, and a lot of my school websites would not work either. I had a lot of trouble trying to download or upload any files.
I could not turn my computer off (or log off my username). The computer didn't freeze; I could still move the mouse around and even open programs. It was as if the computer never processed the request. I even tried from the Windows Task Manager window (Ctrl+Alt+Delete.. under the Users tab).
Finally, the last time I attempted to turn it on, a window came up in the lower corner that said "low virutual memory." The problem is, I cannot imagine how it is possible to have low virtual memory when it's a brand new computer and I never downloaded any extra programs onto it.
It seems like every time I have run into this sort of problem in the past (spyware, adware, any type of virus /internet worm) no program ever solves the problem. Adaware, spybot, ewido, AVG, (clearly Norton Antivirus failed me) has never been 100% effective. Is it possible to dream of a real solution without having to reinstall windows? (I pray there is a way because I believe my mother threw out all my system CDs along with the laptop box when I went back to school this semester.. thanks mom.)
