Computer virus ?

[Creepy]

We are randomly getting movie files (of pornographic nature) fired at our computer. Our daughter uses myspace and it appears to come through that. I have a licensed AV CA associates and that runs clean also ADAWARE which always picks up something but only upto TAC 3. I have just installed Noscript within Firefox to try and track it down.
Any further suggestions ?

Sounds like you need something stronger. A - squared free version. http://www.emsisoft.com/en/software/free/
This is generally considered a very good tool. You may however have to delve deeper.

You need to configure your Internet settings so as your daughter does not get onto sites that you dont wish her to,
perhaps a friend or a neighbour could do this for you it would be cheaper fhat way. "I hope this helps".
