Question : Fake Antivirus program prevents any application from being launched

We have seen a lot of infections of "Antivirus 2010" spyware, a rogue antivirus program that does nothing but ask for you to purchase the full version to protect your computer.

This program is obviously a fake rogue antivirus, and it prevents anything from being run, be it internet explorer, antivirus programs like MALWAREBYTES, or McAfee and Symantec.  We are also unable to run task manager to even see which process is causing this mess.

In safe mode the same thing happens.  Ideally, is there a way to fix this without going into safemode?  We take care of a lot of computers remotely, and this infection is hitting many PCs.
