No, but the problem seems to of been solved.
Hijackthis showed swin32.dll and nsem215.dll, i was suspicious of the the latter, googled it, found it was related to that internet optimizer. I ungregistered the dll, restarted and hey presto! No more error page hijacking
Swin32 was related to automove.exe, though i dont really know what that program did.
Though i can get onto my pull down bar + no popups now
Cheers all and thnx for the links.
