On a friend or family member's computer, download the Malwarebytes installer and update files from the links below, copy them to a CD or flash drive, then transfer the files to the problem machines and use them.. I use the sites below to download the installer file and the manual updater:

Once downloaded and before transferring them to the problem machine, rename the program installer "mbam-setup.exe" file to something else like "Gogetum.exe", then copy the installer file and the update file to a CD or flash drive.. Transfer the file to the problem machine, then install the "Gogetum.exe" file, then run the update to get the program current.. After that, run a full system scan and delete anything it finds.

Next, download the SuperAntispyware program and the manual updater from the links below. After running the Malwarebytes tool above, if you still can't download and install it directly from the problem machine, download it on a friend or family member's computer as well.:

In a few situations, in order for the program to run, it was also necessary to rename the main "mbam.exe" file also after installing it.. It resides in the C:\Programs Files\Malwarebytes Antimalware folder.

After that, a fairly new program called Autorun Eater seems to help as well. Install and run it. See the link below:

Hope this helps.
