problems with firewall and deepguard in CS13

Dear F-Secure-Team,

after updating client from CS12.32 to CS13 (with PM13) and without changings setting anywhere I have problems with the firewall! Problems with FTP: I can open active ftp-sessions, connect to ftp-server but commands like dir, ls, get or put result in errors. Trying to connect with Teamviewer in local network with IP ends in 95% with connection errors. After enabling full network traffic in the FS-CS settings all is fine. I have enabled full access in local network in both directions from beginning. Now I uninstalled CS13 and gone back 10 CS12.32. Now all is O.K. again. I think there must be an error in CS13.

Another thing which is curious in CS13: Gatekeeper recognizes an application as harmfull (which is not). Therefore I make an exclusion and think now it is all right. But next time Gatekeeper blocks the app again. This does not stop until I deactivate DeepGuard and activate it again. Then the app ist not blocked for the next time.

Sorry for my improvable english!

 

Hoping someone from FS can help me. Thanks in advance!

 

Best regards

Martin

    Hey Martin,

     

    nothing new here - support hasnt contacted me yet. I tried to downgrade my Windows 10 Wks to FS 12.31 but that made it even worse. Now, every FSCS (12.00,12.30,..) setup fails, even after I used the FS Uninstall tool.

     

    Fingers crossed:)

    Hello,

     

    > problems with firewall and deepguard in CS13

     

    I'm a but confused about it, but aren't you using the Microsoft built-in firewall with FSCS13 on Windows, because the proprietary "Internet Shiled" firewall of FSCS12 and previous versions  has been removed from the new product?

    Submit the sample here, so the virus lab can fix the false alarm centrally:

    Hello Martin,

     

    Please, contact support. We will need FW debug logs and probably Wireshark logs for investigation.

     

    Best regards,
