There will likely be multiple services installed for Avira, and either one could go missing, become corrupt, or a who knows. Since Avira will have its own services installed, you can see if any services go missing, or if they simply are messed with, when you have a problem again. Have you talked to Avira about this? You might want to keep a close eye on the next Avira install, and then hawk over the services to see what happens. It sounds like Avira has a problem with keeping its service in the Windows service library which is interesting.

If Avira has an integrated firewall system, that could very well be causing a problem this might be fixable in the settings for Comodo, but I'd really have to be looking at your computer to know what is actually happening.

I do know some AV software has extras that act as/are firewalls, so just be careful when installing both. If all you're installing is the Comodo Firewall, and you are running Avira's antivirus only, then I see no problem with that. The computer is a Win8 Pro 圆4 (fully updated with windows updates), Intel 8GB DDR3.Ģ>Comodo Firewall 83.2937, only basic firewall turned ON in 'custom policy' mode, everything else like HIPS & Auto-Sandbox turned OFF.ģ>Windows Firewall (turned OFF in control panel) It's been 6 months, so my question to you geeks, has this problem been solved? Not that this has caused an infection, but I've been using Avira for so long, probably since the Windows 2000 era, and I want to get Avira again. I finally gave up on Avira and started using Windows Defender with Comodo Firewall. Uninstalling/re-installing Avira would solve the issue, but it would re-appear after a few days. On opening Avira, it would say something about the service not running.Īnd I could not start the service in services.msc, it would say 'windows failed to start this service' or something like that. I could install them both (ignoring the incompatibility warning) and they would work for a few days (a few Avira updates), but then Avira's real-time protection would stop, and the option to turn it on would be disabled on the tray icon right click menu.
