are you able to download those programs on another computer and copy them over on a USB?
rename them to a .com extension - they may run with the .com
Try the following
If you have an active internet connection, copy/paste the links below into your browser, don't click them or the rogue might redirect. If you don't have an active internet connection, download the tools from another machine, and transfer them to the affected machine via USB flash drive.
Please download and run the following tool to help allow other programs to run. (courtesy of BleepingComputer.com)

You will likely see a message from this rogue telling you the file is infected. Ignore the message. Leave the message OPEN, do not close the message. Run rkill repeatedly until it's able to do it's job. This may take a few tries. You'll be able to tell rkill has done it's job when your desktop (explorer.exe) cycles off and then on again.
At this point, you should now be able to run analysis tools.
Once the tool has run, do NOT reboot the machine, and then try to run DDS and GMER.
If for some reason the machine reboots, repeat the process. Again, try not to restart the machine.
