Sony Vaio laptop playing random sounds

I hope i have the right board. Anyway I have a sony viao laptop.
It plays random adverts all the time. It also happens when I click play on a youtube videos or the likes. It'll play over the video its very annoying.

I have scanned the laptop with fully updated AVG, NOD32, SPYBOT, MALWARE BYTES, SUPER ANTISPYWARE.
not all at once but installed them one at a time an updated them.
they all found absolutly nothing.

I've uninstalled most programs also to narrow it down but it seems to be none of them.


I've always had AVG up to date so I dont know how this happened.

Does anybody have any ideas? I'd hate to have to wipe the laptop cause im away from home for a few months and dont have discs and drivers etc.

Cheers
