Do NOT download Spyhunter for removal as suggested in the link. Spyhunter has been identified as rouge software, which are either rip offs of adaware or spybot or simply useless/inefficient or downright dangerous.
Download "Spybot search and destroy" and "Ad-aware", then update both programs and run a scan with them. Aslo update your antivirus and run a scan with that too.
Spybot download:

Ad-aware download:

If either of these program find bridge.dll but cannot remove it, then try running them from safe mode.
