Try it

I rooted for CIS complete and bought it again because I tried their previous version and was completely happy about it. This time they have made things even better.

Excellent job

This is the best security suite for this price category and easily gives other brands like Kaspersky a run for the money.

Compatible across all major OS platforms, wipes your computer clean of any viruses, and has a strong firewall to prevent unauthorised access. What else do you need from a cool security tool like this?

I like their new feature TrustConnect that encrypts data upto 10GB/month even if you are using a hot spot to connect to the internet. Very useful feature.

No complaints

Their firewall alone is an industry-leading product that's been embedded in this console. And for the most part it takes care of your protection. But knowing that there are so many strong functionalities makes CIS a must-have security software for everyone.

FAQ about Comodo Internet Security

What makes Comodo Internet Security Complete 8 better than my current Antivirus and Firewall?

Comodo Internet Security Complete 8 adds an additional layer of prevention called Defense+. This is what is known as a HIPS or Host Intrusion Prevention System. Antivirus software is a cleaning tool which scans for known viruses and removes them after they have already taken root. Comodo is a prevention tool as well as a cleaning tool, stopping potential viruses at the door. This works by inspecting each file that attempts to run on your computer and instantly comparing the files to White Lists of good files and Black Lists of dangerous files. If a file is not on either list it is restricted by our Auto Sandbox Technology™ so that you're protected and can still work until the file is added to the correct list and either released or removed. more

Viruscope monitors the activities of processes running on your computer and alerts you if they attempt to take suspicious actions. Apart from forming yet another layer of malware detection and prevention, the sub-system represents a valuable addition to the core process-monitoring functionality of the Behavior Blocker by introducing the ability to reverse potentially undesirable actions of software without necessarily blocking the software entirely. This provides more granular control over otherwise legitimate software which requires certain actions to be taken in order to run correctly. Viruscope works using a constantly expanded list of activity 'recognizers', which allow the software to detect, block and undo many potentially unwanted actions.

Website Filtering

The new website filtering section gives CIS users a powerful and easy way to allow or block access to specific websites. Website access rules can be created for particular users of your computer, which makes this feature very useful for both home and work environments. For example, parents can block juvenile users from visiting inappropriate websites while companies can prevent employees from visiting leisure sites during working hours. You also have the option to create a log event whenever a user tries to visit a website which is in conflict with a rule. CIS ships with several preset lists (or 'categories') of URLs which can be added to rules that you create - including the 'Malicious sites category', the 'Comodo Safe category', the 'Comodo Phishing category' and the 'Comodo Malware category'.

UI Update

The CIS user interface features several design and UX enhancements which allow you to accomplish tasks faster while keeping you better informed than ever before. New themes include the bold new 'Metro' theme.

Process Activity Dialog is added.

Added 'Please call a live expert' balloon message in main GUI when running into 'At Risk' status.

Virtual Kiosk is renamed to Virtual Desktop

Advanced settings window has been redesigned to provide a better layout

Protected Data Folder

New data security feature which makes important files completely invisible to programs running in the sandbox. Files placed inside a ‘Protected Data Folder’ cannot be read, accessed or modified by any sandboxed application.


~700% Faster Sandbox.

All CIS Advanced Settings components are now accessible via CIS Tray menu.

Windows in 'grid view': Improved file search operation and added 'search completed' notification; added 'Jump to Folder' option; columns now retain their widths as last changed by the user.

AV Scan results and Rating scan results windows can be viewed in full screen mode.

CIS UI tooltips now correspond to Windows style

Viruscope is now enabled by default, monitors more activities and works on sandboxed applications as well as not sandboxed ones

CIS can now send security and configuration events to Windows Event Logs

Policy based automatic- sandboxing
