Actually, I'm pretty impressed with CIS 3.8.
I've used Comodo Firewall on two XP's for nearly three years with great success, and it consistently remains the best rated free firewall at Matousec.
I guess I was a bit shaken with Avast a few months ago when I found out it wasn't working properly (
HERE). So I decided to uninstall Avast (only on one system) and install CAV instead. The very first scan with CAV alerted on C:\Windows\mplayerplugin.dll for Unclassified Malware@8381850. A scan at
VirusTotal (file re-scanned for this post, notice Avast still doesn't detect it) revealed 21/39 various hits for trojan, adware/spyware, high risk worm, etcetera. To be fair though, the file wasn't detected either by MBAM, SAS, RemoveItPro, Dr. Web CureIt, or Kaspersky AVK. Before someone tells me to submit the file to Avast, I've already tried and none of my email providers (except ISP based) will accept zipped files.
A point of interest: There are very few requests for help to remove malware on the Comodo Forum. The ones I see are all from newbies who have just installed the program and are trying to get rid of pre-existing problems.
I know Comodo isn't for everyone, but it works for me. Heck, any software, especially security software, is a crapshoot anymore.

is much lighter on resources than Avast.
