If you sent the file to quarantine, then only a few registry keys and junk files are left; however, if this is recurrent malware, it can regenerate itself on a reboot. But you need first to make sure that this is not a false positive by submitting it to Avira, Avast, Norton, etc., for evaluation.
If you want to restore it and to remove it, try downloading a-squared free and Ccleaner from majorgeeks.com or snapfiles.com/freeware and run some scans. Winpatrol from
www.winpatrol.com and SpyBot are very good in displaying ActiveX and BHO malware installed on your PC, each having options to remove the malware.
First, do some googling to make sure that you are not seeing a false positive and scan with a-squared.
Hope this helps.

P.S. I've found that WinCleaner AS Free from
www.wincleaneras.com and AnVir Task Manager Free work well with CAVS and BOClean, and you may want to try these out when you get this problem cleared up.
