Error = 0x7d1 : The specified driver is invalid

March 28, 2009

Solution will be:

  1. Run REGEDIT
  2. Navigate to HKLM\System\CurrentControlSet\Services\[mfebopk, mfeapfk, mfeavfk,etc.]
  3. Modify the ImagePath to be the full path to the driver, e.g. Instead of "system32\drivers\mfeapfk.sys" change it to "C:\Windows\System32\Drivers\mfeapfk.sys"
  4. Then Re-enable Mcafee Viruscan Enterprise 8.7i
