Norton not working, possible virus, PLEASE HELP
Hi, I am having a major problem with my computer. I don't know much about computers so please bare with me:
About a week ago I was looking at youtube videos one afternoon when all of a sudden my screen became VERY distorted, just a jumble of lines and my lap top made a horrible loud noise. A few seconds later the screen went to blue Windows screen, saying Windows had shut down to protect my computer (at top) and at bottom said dumping files with a tally number as it dumped. After restarting my computer I did a system restore to a few days before and everything seemed fine.
A few days later it all happened again. Again I did a restore. After that I noticed my Norton toolbar was gone (I use Norton as a search engine). Then I noticed everything about Norton was not working. If you clicked on the icon on the desktop either nothing happened or a tiny little blank window popped up. I checked and Norton was not turned on. I tried to turn it on and it would not let me. My computer did the same thing with the freezing, distorted image, loud noise several times over the next day. It did not work at all, but now it will do most things except that it is highlited while typing in fields of any kind.
I just tried to uninstall Norton and it won't let me. When you try to uninstall nothing happens, when you try to scan with it nothing happens, when you click on it nothing happens. The program is essentially dead, but it is causing my computer to crash on me, or seems to be. I downloaded Comcast's "Constant Guard" and Norton security suite that comes with it. It states Norton security suite is installed, but then says its status is "at risk" when you click on it nothing happens (won't open).
If anyone could help me I would really appreciate it. (I did check and I have done all windows updates, drivers updated)
