My 12yo son had his homepage hijacked by a supposed antivirus software. I say supposed, because now a porn site pops up. I've checked his cookies and the sites he's allowed to go to are there and there aren't any he's not allowed to, so I don't think he's been porn surfing.

I've been lax and hadn't loaded antivirus software on his computer, I know that was stupid. I've loaded it now and it's keeping the porn popup from coming up. I've run CWShredder, Spywareblaster, and Hijackthis and none have worked. The homepage still won't change. Help.
