My laptop (Windows 8.1, 64-bit) recently was infected with what I believe is the smartservice rootkit/virus. I somehow disabled its ability to prevent MBAR/Malwarebytes from opening, so I can (and have) scanned with them to no avail.
The infection seems to be in two folders located at AppData\Local\pwdacnz and AppData\Local\cwaitrx. It manifests itself as a multiple Windows Process Manager (32 bit) entries which are all named pshlxct.exe
I have also used Roguekiller, Adwcleaner, FRST, GMER, TDSSkiller (didn't work) and Rkill. Roguekiller was able to detect and (I think) delete pwdacnz and cwaitrx at first but when I restated my computer the folders re-appeared.
I recently ran windows update and my windows security should be updated, if that matters at all.
Here are my FRST logs. Here's my mbar log as well. I have access to a USB drive and clean computer.
