My suggested approach: I have used Malwarebytes with great success when cleaning other people's PCs of viruses.
Sometimes Malwarebytes could be installed and run on the infected machine, but if it was a hijack virus it would usually lock the infected PC so I just removed the infected drive and connected it to my PC and cleaned it with Malwarebytes.
To do the latter, for safety, you ideally need to have a decent virus package running (I use Microsoft Windows Security Essentials) and Malwarebytes PRO (the paid version) running on your PC, with Malwarebytes Real-time protection
Enabled (the free version does not have Real-time protection).
See here:
Malwarebytes FREE and PRO - Mini-Review.Make sure you run Malwarebytes and then the virus package over the infected drive, and re-run them both over the infected drive again, after it has all been cleaned up. (Belts and braces.)
Could be worth checking the Malwarebytes website for notes on Trojan Dropper:MSIL/Livate.A, before proceeding with my suggested approach.
