Comodo Internet Security 5 includes the company's free firewall and antivirus program, which together do a great job of keeping your PC safe from even the very latest in malware threats.
Reboot after installation and the program will immediately go to work, popping up alerts about any of your applications that want to go online, or otherwise behave in a suspect way. If you recognise the program and know it's safe, though, just click Allow, Comodo will remember your decision and you won't be asked again. So after a few minutes the pop-ups die down and you can carry on as normal. (Except, of course, now you know you're protected by a tool that's keeping a very close eye on everything your programs do.)
Comodo's antivirus engine sees major improvements in this version. A host of new cloud-based technologies see white listing and malware detection now done in the cloud, enabling greater accuracy and faster detection of new threats. Cloud-based behaviour analysis traps zero-day malware before it can cause any damage. And a new spyware scanner uncovers and removes more malware than ever before.
The suite now also includes a Game Mode, which allows you to run games or other full-screen apps without being hassled by security pop-ups.
And improved application control puts you firmly in charge of what's run on your PC. The enhanced sandbox will successfully run more programs than ever in an isolated environment, where they can't affect the rest of your system. And you can now lock down a PC so hard that users will only be able to run known safe applications, greatly reducing the chance of any future infections.
