Publisher's Description
From Comodo:
Comodo Internet Security 2011 is the free, multi-layered, security application that offers complete protection from viruses, Trojans, worms, buffer overflows, zero-day attacks, spyware and hackers. Built from the ground upwards with your security in mind, Comodo Internet Security combines powerful Antivirus protection, an enterprise class packet filtering firewall, advanced host intrusion prevention, application control and anti-spyware in one supremely powerful application. The latest version sees a major leap forward in security and usability with the addition of cloud based virus-scanning and behavior analysis of unrecognized files - making CIS 2011 unbeatable at detecting zero-day attacks. Under default settings, unknown and untrusted files are automatically scanned by our cloud-based virus scanners then, while the file undergoes behavior analysis on our cloud server, it is run in a sandbox on your local machine so that it cannot modify or affect data on your 'real' system. Put simply, this ground-breaking method of protecting your PC means that only trusted applications are allowed to run on your computer. Malware and untrusted files get nowhere near anything important AND you get to use your computer without interruption from nagging alerts. CIS 2011 also features a friendly graphical user interface; granular configuration options; easily understood and informative alerts; wizard-based detection of trusted zones and much more. Comodo Internet Security delivers enterprise class protection and can be used out of the box - so even the most inexperienced users will not have to deal with complex configuration issues after installation. Comodo Internet Security is available in many different languages and is free for life.
What's new in this version: Version 5.10 has improved Compatibility with other security suites is improved in Windows 7 x64 and fixed Smart scan crashes under certain circumstances.

"Cis is simply the best option for personal PC security"
Version: Comodo Internet Security 5.10
Pros
CIS Free,low resource usage, solid anti-virus,sand box,best fire wall and mall-ware protection. If you are looking for PC security this is the one to get. No other package free or paid can beat CIS
Cons
Some novices might find the initial firewall warnings a bit much. Cis remembers your decisions though, so these warning becomes few over time.

"2 in 1 but blocks safe sites & lets enter real menaces!"
Version: Comodo Internet Security 5.10
Pros
As far as I know, only Comodo offers a full protection combining a free antivirus and a free a firewall at the same time... If I'm wrong please let me know searching for another free antivirus and firewall protection 2 in 1...
Cons
The main problem with Comodo is that on one side it seems to overprotect unnecesserily your PC or laptop by blocking several safe (!) sites of yours but on the other side lets enter real menaces detected by Avast for instance!!! How come?! A few weeks ago, I tried to ask Comodo antivirus support regarding this issue but recevied no reply in return! Therefore, I was fed up of that and redownloaded the last version of Avast combined with Zone Alarm firewall seen that Windows firewall doesn't work anymore on my laptop!...
Summary
@ Tydicea : Thanks for your advice! I'm very happy to learn that. Question : according to Cnet.com, the new Zone Alarm security and firewall free suite is good. So, if you tested both, which one would you recommend? Agnitum Outpost Internet Service or Zone Alarm Internet and Firewall free Suite?
Updated on May 2, 2012
Updated on May 6, 2012@ Jon123 : That is what I did. I uninstalled Avast for ZoneAlarm Internet + Firewall. I will give it a try and see how efficient it is. Thanks. -

"Fails The Big Tests"
Version: Comodo Internet Security 5.10
Pros
There is a "free" version.
Cons
It fails a lot or tests.
Summary
I am participating in a thread on the COMODO Forum for COMODO Internet Security and it has come up numerous times how great CIS has done on the Matousec test to which I replied...
I had to research Matousec as the first time I ever heard of it was in this thread. As far as I can tell, they test firewalls but make more demands of firewalls that are kind of silly such as key logging. A firewall should protect against and stop leaks. The anti-malware part of the program should protect against and remove malware. Yet Matousec tests with the anti-malware portion turned off.
It also appears vendors can pay Matousec to retest giving the vendors the right to either publish the results or not publish them. This is a mafia-style extortion tactic...
"Hey your product didn't score well in out test. If you don't want the results published, pay up and we will retest it and if the results are still not good then we won't publish any results. This is an offer you can't refuse!"
And apparently they score the results of 10 tests across 11 levels even if they all are not run. Take ESET for example...
http://www.matousec.com/projects/proactive-security-challenge-64/reports/PSC64%20report%20-%20ESET%20Smart%20Security%205.0.94.0.pdf
In the latest test it got 33% but only ran in 6 tests. Take the total product percentage of 360 and divide it by 6 and it is 60%. All tested products need to be ran across all tests.
I found a lot of criticisms against Matousec...

http://www.wilderssecurity.com/showthread.php?p=189909
http://www.dslreports.com/forum/r20905485-firewall-tests
So in taking all of this into account, Matousec is meaningless to me. I still want to see CIS kick butt at real tests like the VB100, AV-TEST, AV-Comparative, ICSA, and Checkmark. It is not the responsibility of the end user to independently test security software to find the best one. -
"ITS NOT AS YOU THINK... IT SUCKS!"
Version: Comodo Internet Security 5.10
Pros
1-FREE
2-Firewall is a bit goodCons
1-Their Antivirus is a JOKE. It has huge of False Positives that will make you feel like crazy! sometimes it detects windows files as viruses, and their Cleaning Essentials is even worse..I remember that it detect some of itself files as viruses. LOL
2-Full of bugs! it has like 100 bug.
3-It doesn't protect you well..
4-There are FREE Antiviruses which gives you better protection than Comodo AV.Summary
Im pretty sure that you can find better Security software and for FREE also. you can try avast! Antivirus (always use the newest version) and if you need Firewall, you can try PrivateFirewall or Online Armor Firwall or ZoneAlarm Firewall. ALL FREE and better than Comodo.
by the way, Comodo isn't like what people think about...it sucks big time and I know. my advice is FIND SOMETHING ELSE. -
