At first I like to thank you guys in Comodo for giving me free lisence to Comodo Internet Security Complite! 
I have two OS in my computer in dual boot: Windows XP SP3 (32-bit) and Windows 7 (64-bit). In XP Im using F-Secure IS 2010 which I have won from Mato78.com (=its a finnish hardware site). In Windows 7, I used first F-Secure IS 2011 beta, because it`s free about 6 months. I uninstalled F-Secure IS 2011 beta from my computer by using Revo Uninstaller. Then I installed Comodo Internet Security Complite. I play a lot of computer games like BF:BC2, TF2 etc. I have been experiencing langs in BF:BC2 when respawning back to game. Since I installed Comodo my problems in BF:BC2 vanished ;D. Comodo ISC is also much lighter on RAM than F-Secure. Comodo uses only 10-20MB of RAM when F-Secure uses about 70MB.
Comodo firewall is asking more about connections and software than F-Secure but it`s not a big problem to me. Comodo also detects my XP´s F-Secure virus signatures to UnclassifiedMalware[at]107915481 and UnclassifiedMalware[at]107911752. I know that those are FP´s but I can´t move them to My safe files. I don´t know is this FP or not but Comodo also detects some XP´s System Volume Information file into UnclassifiedMalware[at]105078777. I can send these files to you guys to study :a0
EDIT: When I go to Scanner Settings there is a spot: Do not scan files larger than (MB) and value 20. Why it is just 20? What about 30MB or 40MB? What happens if I download file which is over 20MB and it contains virus(es)?
