i was surfing the net and suddenly i got a blue screen full of text of which i could only glimpse 'any windows updates you may need' and then it blinked out and shut down and rebooted. zone alarm came up asking me if i took enough care to prevent viruses and offering me the pro version, and windows said it had covered from a 'serious system error'. the next time i booted, it said my current settings did not allow active x so the page may not display properly. on this active desktop recovery screen, there's a blank transparent square that looks as if there was a picture on my desktop but it cannot be displayed for some reason. but i never had any. everytime i boot i get this now. i ran avast, avg, spybot, ewido and adaware in safe mode and they found nothing. what would you advise? thanks in advance.
