Try one of the on-demand scanners, which I have ranked in this order: 1. Hitman Pro 3.5; Malwarebytes' Anti-Malware; 3. Comodo Cleaning Essentials; 4. SUPERAntiSpyware; 5. Norton Power Eraser. Emisoft Anti-Malware 6.0 is also good for removing bearshare, but Hitman Pro contains the two scanners in Emisoft...the Emsisoft Anti-Malware, and the Ikarus Anti-Virus engine..., in addition to Dr. Web, Prevx, and G Data...and would be my first choice.
