"Total protection against all malware – free"


Don’t know how to secure your PC from viruses, hackers and spyware? Comodo Internet Security is your solution! It is a free, multi-layered security program which offers complete protection to your pc from Trojans, viruses, buffer overflows, worms, hackers and spyware. The application is a supreme powerful one, thanks to its combination of Antivirus protection, firewall filtering packet, advanced prevention for host intrusion, anti-spyware and application control.


Comodo Internet Security is very easy to install, with it having a self-extracting installation file. You will have no surprises during the first stages. After you accept the license agreement, you must choose the folder where you want to install the program. You will then be presented to choose to install the Firewall and the Antivirus components of the Comodo Internet suite. It is recommended to check both boxes. Before you install it, you must be sure that you don’t have any other security antivirus programs. You should remove them. The installation is fast and smooth. After you finish installing the program on your screen will appear a message to join the Threatcast community. By performing a malware scan the installation of Comodo Internet Security will be complete. All in all, the installation process should not take longer than 3-5 minutes without the scan that varies for each computer. The requirements are 128 MB RAM and 350 MB available hard disk space.


Comodo Internet Security has a user-friendly interface. It can be very easily understood and gives informative alerts too. It includes granular configuration options and for trusted zones wizard-based detection. Thanks to wizards and preset policies the firewall simplifies the process of the rule settings. The main interface will show you on the left-hand side the system status and also recommendations on how to perform some actions. The navigation between each firewall module is quick and easy.


Comodo Internet Security has an advanced driver level of protection which will defend your PC against Trojans that have their own protocol drivers. If the program doesn’t recognize some files or they are not in Comodo’s white-list it will send them to Comodo Instant Malware Analysis server for an analysis. After the files are tested and executed in the virtual environment of Comodo servers to see if they are having a strange code, the results will return to you in 15 minutes. The management module of the program is vastly improved. It allows you to export records of Firewall, Defense+ and Antivirus activities thanks to its user-defined filters.

Both the advanced and beginner users can benefit from this essential troubleshooting feature. The firewall features 'Comodo Safe-List Database', an extensive white-list of safe executables. Every executable will be now checked and if the firewall thinks it can damage your PC, it will alert you before you will install the application. Comodo Internet Security has the ability to protect your system files, processes and registry entries. If you have problems with the buffer overflow attacks, the tool implements protection against them and as a result, you will immediately be alerted by a pop-up message. It protects you against computer crashes, data theft or system damage. If it finds untrusted files, it will quickly isolate them, thanks to its Sandbox feature.


The only problem is that it takes a few days before it will configure properly on your PC. You will constantly receive alerts in the first few days for every single app, even if it’s a trusted one. But like other security programs, such features are common. So don’t be scared to try it! You might not want to get rid of it.
