Hello Olivier,
Thank you for your message.
Unfortunately, this is a pretty common practice for the new releases since modern a/v software detections are almost entirely based on statistics, AI and heuristics - it will take some time, perhaps, a couple of months before the dust with the false positive detects settles.
However, please note that we send false positive reports to the antivirus software vendors on a regular basis, so that they can remove the false positives. In this case, you've already submitted a false positive report, so hopefully the AVG team will resolve the issue as soon as possible, since it's coming fr om their own customer.
Unfortunately, our assistance with the antivirus-related issues is very limited since we have no control over their software or detects - in this case, we can suggest temporarily disabling the antivirus when installing Host and adding the Host installation folder
C:\Program Files (x86)\Remote Utilities - Host\ to the exception list as described
here before turning the a/v back on.
In case if AVG only removes your custom Host installation package, as a temporary workaround please try installing vanilla Host from our
Download page first, then adding the installation folder
C:\Program Files (x86)\Remote Utilities - Host\ to the AVG exception list (I also suggest adding the folder wh ere you want to store the custom installation package to the exception list as well). Then you can run your custom Host installer over the existing installation - this will update the default Host settings and overwrite them with your custom ones.
Please let us know if you have more questions.
