The issue with 17.7 with the passive mode is still not fixed.
Especially if you have an old version of AVG though you removed it completely it will still switch to passive mode when you install the new version whether the 17.7 or this new beta 17.8. It will say that the conflicting AV is the old version.
Hi J.Bryl there are several issues with passive mode and we have a plan to test it further - the scenario you described will be retested too. However, if you were not already asked to do so, could you please enable debug loggin (Settings -> Maintenance -> Enable debug logging), restart the machine and send us all logs from ProgramData\Avast Software\Avast\log\*.log (or ProgramData\AVG\Antivirus\log\*.log if you have AVG) in ZIP archive?
If you have troubles with uploading to
