If quarantine is not possible, try to scan your system using antimalware:
Malwarebytes Antimalware (MBAM) http://www.download.com/Malwarebytes-Anti-Malware/3000-8022_4-10804572.html
You can also download it from http://www.gt500.org/malwarebytes/mbam.jsp
Install the program, allow the installer to get the updates and launch MBAM.
When update is finished, click the Settings tab. Put a check on all boxes.
Run a quick or full scan.
+++++ If MBAM will not install, please rename the installer mbam-setup.exe. Example: newtool.exe
Proceed installing the renamed installer of MBAM.
+++++ If MBAM will not run, go to the program directory of MBAM (e.g. C:\Program FIles\Malwarebytes Antimalware\) then rename mbam.exe to newtool.exe, double click newtool.exe to proceed in running a quick scan.
+++++ If you can't update MBAM, manually download the database installer from http://malwarebytes.gt500.org/mbam-rules.exe
