There seems to be an uptick in Political comments in recent months. Those of us who are long time members of the site know that Political and Religious content has been banned for years. Nothing has changed. Please leave all political and religious comments out of the forums.
If you recently joined the forums you were not presented with this restriction in the terms of service. This was due to a conversion error when we went from vBulletin to Xenforo. We have updated our terms of service to reflect these corrections.
Please note any post refering to a politician will be considered political even if it is intended to be humor. Our experience is these topics have a way of dividing the forums and causing deep resentment among members. It is a poison to the community. We appreciate compliance with the rules.

I'd try F-Secure too. It has the advantage of not being on your PC until the scan starts so it isn't likely to be affected. Most of the sites I saw described removal as more or less deleting all custom or personal browser settings, but can't say if this gets it all or if it will assert itself again. Sometimes a System Restore will do the trick as well. Did you try scans in safe mode?
