Comodo firewall (antivirus and intrusers) problem

My Comodo Firewall 3.0 is always blocking intrusers. In 2 hours it blocked out 3000 intrusers. In the firewall register the intrusers are from Windows Operative
System and C://Windows/svchost

Is this normal?
Another problem is everytime the antivirus actualizes, the Defense + of Comodo alerts to 3 files that are modifided.
Is there a way to resolve this problem??? For it to actualize and stop asking the same question???

How do i resolve these 2 problems??

Thank you

Welcome. :slight_smile:

what is svchost.exe set to to in your network policy.

Go to Firewall > Advanced > Network Security Policy

Are you behind a router?
Windows Operating System logs are not really intrusion attempts. In other words, they are normal and aren’t anything to be worried about.
