CF blocks Internet connection.

Hello!

For some last releases I couldn’t use CF as my PC got freezed after its install. After smart advice from blacknight at Wilders I used this Comodo removal tool 2014. As it was prescribed I run this tool in Safe Mode. CF was OK for some hours then I found out that it blocks Internet access for all applications. When I switch off CF then Internet access restores. Please help me.

Just found out the following. This happens when I enabled “Anti-ARP spoofing”. I turned it off and now it’s OK.
