This detection was strange from the very beginning. For example, when we tested it yesterday Windows Defender falsely notified as about this "trojan" but still allowed Viewer to run. Then why they call the Viewer a trojan in the first place? :)
Anyway, we have already received a response from Microsoft and they asked some more information. We'll make sure that this issue is resolved soon.
Thank you for your message. Yes, this problem was also reported today by a few other users as well. We have already contacted Microsoft regarding this issue. Hopefully, they will fix it as soon as possible.
I perfectly understand your frustration because we are frustrated with these uncontrolled and irresponsible antivirus software behaviors too.
P.S. I will move this thread to the antivirus sub -forum.
No, I didnt clone them, I installed them manually on each computers.
If you installed them manually on three different physical machines and generated the Internet ID in the Host settings it is next to impossible that there are duplicate IDs on even two Hosts, much less three or more :)
Are you sure you have indeed the same IDs on those Hosts? Could you please verify it by right-clicking the Host icon in the system tray and selecting "Internet ID connection settings". The ID will be displayed in a window like this:
1. Check that you have the most recent version of both Viewer and Host. This should be 184.108.40.206 as of this writing. There used to be issues with previous versions and Windows update, as described in this article.
2. If there is antivirus software on the Host computer, make sure you add the Host installation path to its exception list. This is recommended even if you don't have issues with this a/v software so far - you never know when they decide to block or restrict the software next time. A/V programs don't like remote controls much and often mark such programs as riskware.
Specifically about Symantec - there were couple of issues with them recently and each time we reported to Symantec. The last time they responded that the issue was fixed. But if you still have issues with Host settings erased or reset - and this is a sure sign of either a/v activity or Windows update activity - then let us know.
