Command line temporarily disable of On-Access Scanner for data backup

Hi there! How can I use a batch file command line parameter to temporarily disable Avast4Pro’s ‘On-Access Scanner’?
What I need to do, will be done with all network connections disabled (so new viruses during the the operations will not be a possibility).
Since the total operations will take approx. 12 hours, it needs to be done unattended and when finished, shut down the computer.
So, I need to perform the following file operations in the following order on a non system 750GB HD.

NIGHT 2: (Auto Bu)

  1. Manual Disable:
    • Disconnect Local Area Connection
    • Stop: Avast4Pro ‘On-Access Protection’
  2. Run Batch file: X~DATA~Odd or Y~DATA~Even (batch file should re-disable Avast4Pro after any restarts)
    • Runs GBM: ‘01~DATA’ (approximate time required 6:40?) {This is Genie Back Up Mangager Pro}
    • Runs True Image: ‘Monthly DATA True Image’ (approximate time required 5:40)
    • Runs True Image: ‘Monthly D975X True Image’ (approximate time required :06)

Here is the batch file that will do the trick:

2-MoAutoBu.bat
Rem - This batch file runs Night 2 of ‘Auto MoBu of DATA (T:)’
Rem - Runs GBM: ‘11~OMoDATA_Q’
“C:\Program Files\Genie-Soft\GBMPro8x64\GBM8.exe” -e -job “11~OMoDATA_Q” -bt1 -shutdown
Rem - The following ‘Shutdown’ restarts computer
Shutdown
Rem - The above ‘Shutdown’ restarts computer and causes scheduled True Image to run (on following startup)
Rem - True Image ‘Monthly DATA True Image’ runs on startup
Shutdown
Rem - the above previous shutdown causes ‘Scheduled’ True Image to run on shutdown
Rem - True Image runs ‘Monthly D975X True Image’ and computer shuts down

The problem is: the two True Images have to come after the GBM (because of True Image’s limited command line ability). So the True Images have to be initiated by the first shutdown and by the second shutdown (actually a start up). SO I NEED A WAY TO KEEP AVAST4PRO ON-ACCESS SCANNER SHUT DOWN AFTER AN AUTOMATIC RESTART. I will not need virus protection during these massive backup procedures and if AVAST4Pro is uselessly running in the background, on this known to be clean system, it will take many additional hours to complete.

I hope this makes sense, I really do appreciate the job Avast4Pro does. But in this very unusual situation, I need a way to temporarily keep it’s ‘On-Access Scanner’ disabled without having to manually do it by right clicking the ‘a’ icon and 'Stop On-Access Protection. Thanks for any help you can offer… Jay

It’s not possible. avast is not intended to start and run only on-demand after booting.
I don’t know a method to turn a service to ‘disable’ status. After booting, it will start again (as you can only stop the service and not set it to disable).
