Months ago, I downloaded the Comodo Firewall. I frequently use the manual updater, but it always responds that there are no new updates. I’m becoming suspicious. Are updates really that infrequent, or am I experiencing a problem downloading any new updates?

There have been no updates for quite some time. The firewall does not require regular updates in the same way that the antivirus does. Also, the database of applications that are certified as safe has not been updated for ages: this is mostly due to the pending release of the newer version of the firewall which is currently in beta testing.

I would not worry about the lack of updates, everything is likely to be working fine. Keep watching the forums for the release of version 3 though, it promises to be awesome.
