COMODO Firewall PRO - security from the inside out
For all practical purposes you don't need a 3rd party firewall to protect yourself from outside threats. The problem is if you do run into a security problem you likely invited them in.
If you downloaded or installed software or possibly loaded that new codex to a media player from a less than reputable site you could be compromised.
COMODO can help (lets just say, can be the bearer of bad news).
Clean PC Mode takes a snap shot of your installation and alerts you we something new is installed.
Host Intrusion Prevention System does exactly that, prevents modifications of key operating files and prevents access to key systems. This is nice in that when you install new applications if they try to run astray you are aware of what it is trying to modify.
Application Behavior Analysis alerts you when something is trying to call home.
The program even has a very large application recognition database to help minimize the fatigue caused by other firewalls when you have to respond to false alarms.For a complete list of features please see the web site.
