Last week a message appeared on laptop say we had a Blaster Worm, we were supposed to link to a site and pay some money for it to be removed, realised it was a scam so bought NIS 2011 and N Essentials. At this point we could access the internet and not emails. After many hours I finally managed to install Norton in safe mode, cleaned the system, and Norton did everything it should but now I can access my emails without any probs but cannot get the internet explorer 9. My system is windows vista. Can anyone give me any advice please?
