I think that I have rootkit or other malware on my computer.

Okay, I know you're having this issue when installing, so make sure its definatly uninstalled then close all windows, and run this tool:

http://downloads.malwarebytes.org/file/mbam_clean

Doubleclick to run the tool, and it will run quickly. It will ask to restart your computer, please allow it to do so very important.

Next Download & SAVE the latest version of Malwarebytes' Anti-Malware from

http://downloads.malwarebytes.org/file/mbam

(I know you already have, but just delete the previous one you tried, and get this fresh one, just to be safe)


Right-click on mbam-setup.exe and select Run as Administrator and allow to run.

Then after the setup has finished, on the Dashboard screen, press the Update now link.

Let me know if the update succeeds.
