As far I know, net commands can only enable/disable all antivirus protection (ashserv.exe) but not one provider itself.
Avast shouldn’t block anything, just scan. I always doubt when some technician says: disable your antivirus. Maybe because avast shouldn’t conflict with anything else if it is correct installed in a stable computer.
Maybe you can add the Exmerge folders to the Exclusion list of avast resident scanning…
For the Standard Shield provider (on-access scanning):
Left click the ‘a’ blue icon, click on the provider icon at left and then Customize.
Go to Advanced tab and click on Add button…
For the other providers (on-demand scanning such as the screen-saver or the Simple User Interface):
Right click the ‘a’ blue icon, click Program Settings.
Go to Exclusions tab and click on Add button…
You can use wildcards like * and ?.
But be careful, you should ‘exclude’ that many files that let your system in danger.
