Applies to Kaspersky Anti-Virus 6.0 for Windows Workstations (all builds)
This article is relevant only if the Anti-Hacker (firewall) component has not been installed along with KAspersky Anti-Virus.
The following problems may occur when a Kaspersky Lab product 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 Lab applications are functioning in server mode. They re-route all the Internet and e-mail traffic to itself in order to scan it and establish Internet connection with server. It is necessary to have correctly configured rules for the service AVP.EXE in the firewall.
- 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:
- Port of the AVP.EXE process: 1110
- Standard HTTP ports: 80, 81, 82, 83, 1080, 7900, 8080, 8088, 3128, 11523
- Standard SMTP port: 25
- Standard POP3 port: 110
- Standard NNTP port: 119
- Standard IMAP port: 143
- Local port: 19780
If port 1110 is closed, the process AVP.EXE will start trying all other ports within the 1110 - 2110 range unitl it manages to find an open one.
