"Insecure Internet Activity" Win CP Antivirus page keeps popping up - Help!

[justbeme]

I have Norton Antivirus installed, but since my Daughter did something on MySpace, every few minutes a page pops up and covers the screen saying
"Insecure Internet Activity - threat of virus attack etc"
and then it ask you to connect to a website to buy their Antivirus package.
After running a Norton Scan, nothing is found. I've just upped my security settings and pop up blockers and its STILL popping up. It throws me out of Facebook and also Mumsnet - so I need to get it sorted!!!
Any other ideas please??
ps I'm not too computer literate!!
Many Thanks.

Take a look at "AddRemove Software" (in Control Panel) and see if you can see this in the list to uninstall. There is a chance that it's actually listed there since the makers might not see it as an attack, but a legitimate form of advertising. If you're not sure then post the names of items that sound like it.

You might want to run Spybot since it searches for different kinds of things to antivirus software.

Is it definitely calling itself Win CP Antivirus or was that a typo for Win XP Antivirus because there is one called that I think.

There's a virus doing the rounds which mimics WinPC. It pops up with lots of screens telling you that someone is in the process of downloading your data via the internet and that you need to install WinPC. It's a fake. If you look really closely at the wording it's a bit 'off'.

Spybot will get rid of it for you.

The virus is apparently rife on some of the FB applications. I think it came up on spybot as something like "False WinPC" and something called "DeepDive".

Thanks very much - I wasn't sure if I could have Spybot and Norton on my system at the same time, but it seems to have worked!!
Spybot called it "Fraud.winpdefender" - although it said it couldnt get rid of it, but it found lots of other things related and so far it seems to have worked.
Cheers!!
