I am an avast user not avast team member and don’t use AIS - so I can’t speak from personal experience.
The Alwil Software directory Is/Was for older versions of avast typically avast5 and earlier so is very old and I don’t even know if the AIS product was around at that time.
The Alwil Software directory was also present for avast Home/Free and avast Pro (no firewall on either product):
- If the user retained either of these products and just did program updates from the user interface, then the historical program folder and registry entries would remain the same.
- If the user at any point did a clean install of any avast program version later than avast5 then there would be the change to reflect the new company name Avast Software, rather than
So it is somewhat hard to say if it was installed or not based on the name Alwil Software.
