Uninstall Malwarebytes first. Next, download the "rkill" file from one of the links below, then run it to help allow the removal programs below to run. (courtesy of Grinler at BleepingComputer.com)
There are 4 different versions. If one of them won't run then try to run the other one. Be patient.... as a black window should open, then close after finding all the background programs.
Vista and Win7 users need to right click and choose Run as Admin
You only need to get one of them to run, not all of them.
Once that's done, reinstall Malwarebytes, update it, then run a full system scan with it.
And just as an aside, I use SuperAntispyware on this Windows 7 Pro machine and have had no problems so far.
Hope this helps.
Tried to download up dates and got this message. Now the program wont work at all. Should I delete Malwarebytes program and try a new download?
