I have the same problem, tried all the exemptions that need to do, still can't use TeamViewer.
Does anyone have the answer to this?
had a same issue.. Open Bitdefender go to Protection tab. First do exceptions in Antivirus tab and than in ADVANCED THREAT DEFENSE tab - Add applications to exceptions - and select all exe files in Teamviewer folder - worked for me
I think need write about false positive detection
Same problem here with Bitdefender Antivirus Free edition. Adding all .exe files (in program files and appdata) to exceptions does not solve the problem. Worked fine before.
1 - Add exclusion
2 - Add File
3 - C:\Program Files (x86)\TeamViewer\TeamViewer_Note.exe
If the problem not solved, add all other .exe files with same method.
I tried again.
First remove all exclusions. When team viewer process (connection test, loading icon) panel open.
Add .exe files one by one. wait 10 sec. each time.
the problem is solved until the last file is added. (for me).
tried the same. Doesn't work at all :-(.
I even uninstalled and shut down Bitdefender Internet Sec..
Windows Firewall INACTIVE. So there is nothing which could block Teamviewer.
Teamviewer 14 simply doesn't connect. Before The Windows 10 Restart everything was fine. (???)
Addition: I downloaded the newest Teamviewer 14 version (already used 14 before, but there was a newer 14-version provided) and now it works fine.
