You could try this, go to a clean computer, download Malwarebytes (free download) send to a flash drive, go to the sick system, boot into Safe Mode with Networking, input the FD, run scan with MWB, see what it picks up, attempt removal.This is a simple basic starting point and may do the trick, good luck!
I have a computer with windows 7 which has this virus on it: Trojan/scratch/virus/M2f318a54.exe. Does anyone know how I can get this off of the computer?
