I have had avast for 3 months using their beta, during this time I have had no issues. In this case you could add DugiGuides_1.5.0.exe to the exclusions list.
Another possibility of this is the rather unusual file extension “_1.5.0.exe” not a typical .exe.
If you need help adding it to the exclusions list please let me know the product and version so I can lend assistance, bare in mind when a new dugi installer version gets released you will need to change the shortcut to new file name and add it to the exclusions list.. again.
