In the past i have always/often to report selfcompiled fpc and it tools to Avira, because the software detects and blocks it. After the reporting in 1 or 2 days it was no problem to compile. I think if the issue is reported, the AV-Provider will update their reporting.
Report, report and report, so the AV-Providers will have a look to get their product less producing positive false.
Now Avira is not useable for me, becaus with the last changes it installs a lot of unwanted software and i can not inhibit this. The Support have checked tis and the official answer was 'It by design'. Ok, with this design i have closed my paid subscription (it too - by design).
