lap top hanging frequently -- need help in this regard I use hp pavilion laptop and i have original Norton Anti Virus 360 premier installed in it. The problem is my lap top gets hung frequently and this problem didn't arise when i run NAV everytime i go online. I go for full system scan everytime but i didn't receive any threat from viruses or malware when scanning was finished. But if i fail to run NAV simultaneously with my browsing, at some point of time my system gets hung? What could be the problem? Members, please help.
