Help !!! Internet history is adding sites i never visited!!!

Tiz ok. It was being hijacked. Zonealarm just blocked a hijacking, then it said it was trying to hijack every couple of hours. It was automatic though. ah well....zonealarm just wasnt properly updating, so i downloading the new version and it found it out.

Thats one of the first things I asked and told ya! Update that #. A few weeks ago my sister called me that her PC was crapping out on her. Turned out her latest AV defs were 1.5 years old, Adaware was never updated and her Windows XP installation didn't have a single WindowsUpdate installed.

Anyways, I still suggest you secure you WAP!
