so i went and bought virus/spyware protection and downloaded it and run virus scans on my computer everyday or every other day. but almost every time i go to a website, i still web pages popping up advertising some random thing, even with pop-up blocker. also random times my computer screen will go blank except for my background on my desktop, icons and all so i will have to restart my computer……all i know to do was get virus protection from best buy so im not sure if there is still somethin wrong or not.
