Sorry in addition I found the below and tried it....I got as far as 'Browse to Non-Plug and Play Drivers and you should see something like TDSSserv.sys' - I could not find TDSSserv.sys undering NON-PLUG AND PLAY DRIVERS.... Please try the following routine to see if you can get Malwarebytes to run. Click on Start, click Run, and then type devmgmt.msc and click OK On the View menu click on Show hidden devices Browse to Non-Plug and Play Drivers and you should see something like TDSSserv.sys Highlight that driver and right click on it and select DISABLE Now RESTART your computer. Download a copy of Malwarebytes but DO NOT run it yet. Rename the downloaded installer file to any generic name such as your own name but keep the .EXE extension on the file and run it. Once the program is installed go to the UPDATE tab and try to update the program if you can. Then go to the SCANNER tab and run a Quick Scan and allow MBAM to fix anything found.
