FAQ for Comodo Internet Security

1. What makes Internet Security better than my current Antivirus and Firewall combo?

Internet Security is a security suite plus. More than just an antivirus program, it also includes an award-winning firewall, host intrusion prevention, a sandbox for untrusted software, anti-malware and buffer overflow protection to deliver comprehensive protection against today's diverse range of threats.

2. What makes Comodo's Internet Security product different from the others?

It's simple: prevention-based, Default Deny Protection. It works by only allowing trusted files to run on your system. Files that are not trusted are run inside the new sandbox

3. What is the sandbox and how does it protect me?

The sandbox is a virtual operating environment created within your computer for unknown and untrusted programs. Internet Security automatically runs untrusted programs in the sandbox where they cannot make changes to processes, programs or data on your 'real' system. This protection goes well beyond traditional Antivirus software by ensuring any brand new viruses are completely isolated and cannot cause damage.

4. Will programs run OK in the Sandbox?

Yes. Applications in the sandbox are run under a carefully selected set of privileges and will write to a virtual file system and registry instead of the real system. This means untrusted (but harmless) applications have the freedom to operate as usual while malicious programs are prevented from accessing or infecting your computer. This provides smoothest and most secure user experience possible.

5. Do programs stay in the Sandbox forever?

No the sandbox is the first part of a trust decision engine. After an unknown application has been placed in the sandbox, Internet Security will also automatically queue it for submission to Comodo labs where it will be analyzed by our technicians. If it is found to be harmless then it will be added to the global safe list that will be downloaded by all Internet Security users in the next round of updates. Once it is added to the safe list, the application will no longer be run in the sandbox by Internet Security. If it is found to be malicious then it will be added to Comodo's list of malware signatures and will be deleted after the next round of updates.

6. Can I install only the Firewall or only the Antivirus?

Yes you are given the option to install exactly the components you want during setup.
