Sorry. Feel free to post. Maybe it wasn’t my best day 
Can you post the name of this application and a link to download it? Is it a freeware?
No doubt, seems a very good tool 8)
The only thing I can do know is testing this application in my computer…
I can’t imagine why avast is doing this but, can you uninstall the Script Blocker (Control Panel > Add/Remove programs > avast antivirus > Remove/Change and then un-check this module) and see what we get ???
