avast!service in the application rules

[WalterWhite]

Hello,today I got a popup from avast internet security 2014.9.0.2007 that avast!service has been configured by the firewall automatically to allow it connect to the network.The only problem is that I already had it configured in the application rules.Now I have 2 avast!service in the application rules,one with the right signature and path,while the other with no signature and has "System" as a path.Cany anyone explain what is happening?

I think that a failure of firewall.yo had is a firefox on micrososft group rule and put signature system... delete it and be returned to correctly create the named system

Everytime I delete it , after 5 minutes avast reconfigures it automatically.
