I just cleaned an offline computer. The FAQ for this was helpful, thank you. To reiterate, I fully updated my version of MBAM on a clean, network connected computer. I put the latest binary plus the newly updated "rules.ref" file onto a USB drive: C:\ProgramData\Malwarebytes\Malwarebytes' Anti-Malware\rules.ref -- was where I found it on the clean computer, you might have to find your own install folder I installed the program (from the link above) on the infected computer, and overwrote the "rules.ref" file (save the original as rules.old just in case) It worked to get rid of some newer nastiness, including a root-kit that was logging who knows what... Thanks!
