What to do

  2. Extract the file to a folder of your choosing.

  3. Click Start and type Command Prompt in the search field. Right-click Command Prompt and then click Run as Administrator.

  4. Type the location/directory where you extracted the script and type Fixupdate.vbs and then hit Enter.  e.g. H:\fixupdate.vbs

For 64-bit systems: C:\program files (x86)\Sophos\AutoUpdate\Almon.exe

Note: Alerts on the Console side will still need to be Acknowledged, and all output log files should be kept for reference until you are satisfied you have resolved all problems with the computer(s).
