Again, is installed in the system32\drivers folder via a hidden .sys
Solution :
-Use
GMER to identify the hidden .sys file (Rootkit)
-run
COMBOFIX (make sure you install the Recovery Console as well, as the fix results in an internet loss, you have to restore your normal internet settings)
NOTE : If combofix doesn't run, rename the combofix.exe to whatever you want and try again
-run
MBAM, it will then detect and remove some leftover strings
Hope this helps
