A computer maintenance engineer has given all the BOINC files and Hadley files \"trusted\" status in terms of Kaspersky but the runs are still being terminated, typically after 12-24 hours. He has asked me to ask you which ports BOINC uses. Though he is very experienced, he is mystified as to what is happening.

For external communication with projects over the internet, BOINC uses HTTP port 80. Very rarely, it also uses HTTPS port 443, but so far as I know only WCG uses that one.

In addition, the BOINC Manager and the BOINC Core Client (the \'daemon\') communicate internally on localhost port 31416: this post is also used on a local trusted network if, for example, you wish to view/control a daemon on one machine from a manager on a different machine.

All port usage is TCP/IP only.

Within Kapersky, is there a way to exclude the BOINC and BOINCData folders from all scanning (on-demand and scheduled)? I would try that first. A number of users have done this with various AV programs to decrease the chances of screwy updates from the AV vendor deciding BOINC or some science application is malware. Of course it\'s up to you if you feel comfortable doing that.

It looks like your last completion was from Feb 11th. Everything downloaded or running after that died at some point with lots of \"no heartbeat from core client\" messages. When did you switch AV programs? Did you make any changes to your hardware or software sometime around mid February? Changes to your BOINC configuration?
