Kaspersky Anti-Virus 2014 and third-party firewalls: co-working features

Back to "Troubleshooting"
2013 Jul 31 ID: 10307

The following problems may occur when Kaspersky Anti-Virus 2014 works with a firewall of another vendor:

  • cannot send / receive e-mails;
  • Internet pages are not (fully) loaded;
  • computer disconnects from Internet either immediately or soon after establishing a connection.

The reason is that Kaspersky Anti-Virus functions in server mode. The product re-route all Internet and e-mail traffic to itself in order to scan it and establish Internet connection with server. Kaspersky Anti-Virus 2014 also scans traffic transferred via different ports which are used by different popular applications.

In order to eliminate the problem, it is required to create permissive rules for the AVP.EXE process in the firewall. In order to do this, perform the following actions:

  • If the installed firewall has a learning mode, enable it. If the AVP.EXE service tries to establish connection, the firewall should inform the user about it. Allow any network activity to the service AVP.EXE.
  • If the installed firewall does not have a teaching mode, create permissive rules for the AVP.EXE process manually for the following system ports:
    • system ports:
      • Port of the AVP.EXE process: 1110

If port 1110 is closed, the process AVP.EXE will start trying all other ports within the 1110 — 2110 range until it manages to find an open one.

      • KSN port: 2001
      • Standard HTTP ports: 80, 81, 82, 83, 1080, 3128, 7900, 8080, 8088, 8888, 11523 
      • Standard SMTP port: 25
      • Standard POP3 port: 110
      • Standard IRC ports: 113 194 6667 6668 6669
      • Standard NNTP port: 119
      • Standard IMAP port: 143
      • FTP-port: 21
      • HTTPS port: 443
      • SMTP SSL port: 465
      • NNTP SSL port: 563
      • IMAP SSL port: 993
      • POP3 SSL port: 995
      • Local port: 19780
    • ports used by applications (different ports may be specified in the Kaspersky Anti-Virus 2013 settings):
      • ICQ/AIM port: 5190
      • Jabber port: 5269
      • Jabber/Google Talk port: 5222
      • Jabber.Google Talk (SSL) port: 5223
      • MSN port: 1863
      • Mail.Ru Agent port: 2041
      • Yahoo! ports: 5101, 5050, 5001, 5000
      • uTorrent: 6969, 6881 — 6889
      • Skype: any port higher than 1024 or the 80 and 443 ports

If after creating permissive rules applications display errors concerning connection problems, create permissive rules for applications and their ports in the installed firewall settings.
