RE: CIS vs KIS
Antivirus
Kaspersky has been tested by many independent organization and while I've personaly tested CAV and found it to be actually very good , the final winner until COMODO will submit their antivirus engine for testing can be only one : KAV.
W: KIS 2012
Extra-Features (HIPS,Firewall,Sandbox.....)
KIS 2012 is the best equipped suite on the market with a lot of security features like
Geo Filter and Application Control that if tweaked correctly might give this suite a really high degree of prevention.
Both suites come packed with some 'must have' features in order to protect a system but the main difference between this two suites is the way they've decided to use them.
W: KIS 2012
Overall prevention capabilities.
With a very well tunned HIPS and an auto-sandbox feature for unknown files CIS wins this battle not only with Kaspersky but with almost all the vendors.
KIS 2012 is has a lot of
tweaking option, and if the user knows how to tweak the settings than the prevention level can dramatically increase.I for one I'm still wondering why Kaspersky doesn't better tune-up the settings for this suite or at least give to the user a 'Pre-Config Wizard' when installing the suite , like it had in the 2010 and previous versions.
W : CIS 5.8
System Impact
Kaspersky is know for beeing a resource hog on some system and this problem can't be solved until this vendor will re-write the basic code for this suite like System did in 2009 for NIS, on the other hand Comodo has constanly improved there resource usage so at this point this suite is very light.
W : CIS 5.8
Usability (User friendliness)
The addition of the Auto-Sandbox feature on CIS made this suite very usable in the real world as it will automatically give limited rights to the unknown files so this should seriously reduce the alerts generated by the HIPS component.
I had this suite installed a few days ago on my system(6 games , 20 apps) and I've only received an alert from the Firewall component so COMODO has made some good steps in the right direction.
KIS 2012 has also bundled a HIPS but unlike COMODO this suite will automatically take the decisions for the users so it will not generate any alerts but this will also mean that the level of protection will be lower.
W : KIS 2012
FINAL VOTE : CIS 5.8
