I have been following the posts on similar topics and tried the suggested steps. Only Malwarebyte's Anti-Malware even finds this thing, but at the suggested reboot after removal, all of the infected files remain as if nothing was done. As a last resort, I completely wiped the hard drive and reloaded windows only to find out that it has completely survived the whole process. I am thinking that this got into the RAM or the BIOS at this point. So, is there anything that can be done? Here is the MBAM log:
