Hey,
My computer has had many problems over the past few days. First, I began getting redircted from Google searches to various ad websites when I clicked on a link. Stupidly, I deleted my account to attempt to stop the spread of the malware or whatever was causing this. I then downloaded Avira Antivir and CCleaner. Avira was a pain because it popped up constantly and sometimes wouldn't go away, so I uninstalled it and used CCleaner which seemed to get rid of the Google redirect issue.
The next day I got a message about 90 seconds after logging on to my computer saying "Services and Controller app encountered a problem and needed to close"and shortly after another message popped up: "Windows has encountered a critical problem and will restart automatically in one minute". After it restarted I tried again with the same result. I can't stay on long enough to get logs or anything. Now these messages come up immediately after logging on.
Another weird/possibly relevant thing with my computer is that the Welcome Center pops up everytime I log on which hasn't happened since I first got my computer.
I have Windows Vista Basic.
Thanks for any and all help on the matter, it will be greatly appreciated!!!
