Used it successfully to set up and delete shares on Home Server as a Windows service (which is started automatically at switch-on).

Now I switch on my connected external usb hard drive and the shares are set up; switch off and the shares are deleted.

Exactly what I wanted to do.

Thanks a million!

While performing some debug tests, I did a few experiments and it turned out that avast’s ashquick.exe did not accept %d: as a placeholder, but it had to be corrected into %%d:\. That way it worked just fine.

Here are debug messages using %d:

[1348] ***OnDeviceChange entered
[5104] Drive V: inserted.
[5104] Volume name:
[5104] Serial number: 84DCA30F
[5104] Filesystem: FAT32
[5104] “D:\AVAST Software\Avast\ashquick.exe”
[5104] “D:\AVAST Software\Avast\ashquick.exe”

And using %%d:\

[1348] ***OnDeviceChange entered
[5776] Drive V: inserted.
[5776] Volume name:
[5776] Serial number: 84DCA30F
[5776] Filesystem: FAT32
[5776] “D:\AVAST Software\Avast\ashquick.exe” %d:\
[5776] “D:\AVAST Software\Avast\ashquick.exe” V:\

Besides, if you add “/action:chest” option avast will report the scan and move the virus files into its chest, othewise it will launch a pop-up warning you that you got a virus, but it won’t report it. Weird I guess.

Thank you for your support, I hope my findings will be helpful for other users of this very useful program.

Thank you

it does not perform the scan. I’ll try the debug option and I’ll let you know.
thank you

“C:\Program Files\Microsoft Security Client\AntiMalware\MpCmdRun.exe” -scan G:

If this command doesn’t do what you want, try it from a command line and tweak it until you get the result that you want. Then update the arguments to USBVirusScan.
