Help! Audio and pop-up malware / virus, BSOD and error messages!

[123Mags456]

My problem is that i keep getting annoying audio clips playing. They're usually adverts, one of which is for some actimist eye spray stuff among other things! It plays randomly, regardless of a browser being open or not, i also get pop ups at random intervals, one advertises the Grepolis browser game and ipads among other things.

Another annoying thing it does, is in my soundmax program it turns the "Wave" volume to 0 randomly, so even if the master volume is turned up i can't hear anything! Not downloaded anything dodgy either, in fact itunes was the last thing i installed before this problem started.

So far i've tried running a virus scan (Avast!) an Adware scan and Mbam. Nothings worked. Deleted all cookies too, still no luck.

This happened a few days ago, however today i turned my computer on, twice i got a BSOD (didn't think at the time to take a picture / note the error)
and then i got two windows errors where you would normally be given the windows is logging in screen. One said the lsass.exe was not functionining properly, the other said that a driver / program is interferring with a part of windows that is affecting your license and is not allowed.

My operating system is windows XP SP3

hijack this file is attached
