several attacks in a short time

my firewall was attacked 1852 times in around one hour n a half
does any one know what can cause it, or what happened?

is there any way to avoid it for the future, was really scary some times
was n attack per second,

You need to take a look at (and Post) the firewall log so we can take a look at it. :slight_smile: And review your 577 files. An intrusion turns out to be any inbound TCP connection request that gets logged. Are you behind a NAT router? What is your OS and Comodo version?
