Alert for svchost.exe does not come

When I first installed Comodo Firewall Pro I had a open port 135 and I removed the Network Security Policy rule for svchost.exe. After uninstalled Comodo Firewall Pro and again installed I do not get the alert for the svchost.exe by Comodo Firewall Pro It seems that svchost.exe does not make connection with the internet anymore, because I don’t get the alert for svchost.exe. How to solve this problem? Thanks in advance. Kind regards, Mike098.
