After reboot i am still experiencing occasional pop ups but not as many as before.

Can you please take note of what some of the popups say and let me know?

Also - I see you used to have Spysweeper, did you uninstall it because your trial period was over?

Pop ups for: Jamster Ringtones, Cassava 888.com Online Casino, Beech Finance and Freedom Finance and other loan companies. These seem to be the main offenders.

Yes, spy sweeper trial had expired which is why i uninstalled it.

Few more scans for me - sometimes Apropos is known for popups when nothing else shows...
