FAQ and Review

Once Salima and Muhindo had figured out what Comodo Firewall Pro does, it was easy enough to use, since most of the time it just sits in the background working away on its own.

However, they still want to know:

Q: If I don't have a firewall, can you tell me a bit more about the threats I'd face? What are the different kinds of programs that can get onto my computer and what do they do?

A: There are literally thousands of different programs that could enter your computer from the Internet, if it operates without a firewall. There are even Internet 'spiders' that roam all possible addresses looking for computers without a functioning firewall, then reporting this address to the people interested in computer hacking.

Q: If Comodo keeps out all these programs, why do I also need an anti-virus program and an anti-spyware program?

A: A firewall works to specifically restrict access to and from the Internet. It prevents a program or hacker from getting into our computer but cannot protect you from malware that you might download through email, Web pages, or external disks. Anti-virus and anti-spyware programs exist to prevent infection where the firewall cannot. And, of course, these tools can often remove malware that is already installed on your computer.

Q: Are there any kinds of malware I need to watch out for which look like Windows programs (or other friendly programs), but which are actually malware?

A: Unfortunately, there are many such programs. You need to be extra careful about the origins of any software that you download or install. You should not install any software that is not absolutely relevant and necessary to your work, especially on computers that hold a lot of your sensitive data.

Q: How good is Comodo at keeping out hackers?

A: Comodo Firewall Pro is just as good as many other software firewalls out there. The Comodo company is well known in security and Internet authority circles. It is offered free of charge to the individual user and its staff are responsive to user queries.
