SpyBot once a very good tool (back in W98 time) but not anymore, they have a small update once a week... and IObit company...cant trust them after that
Malwarebytes and superantispyware have more updates in one week then SpyBot in a year
so as an extra scanner alongside avast! i would go for Malwarebytes and Superantispyware.... if you look in all the pro removal forums. Malwarebytes is the first tool they run if your AV has failed to detect
So back to your problem...is it still there ?
i also recomend following the guide i linked to above and attach the logs so essexboy can see if everything is OK
