Q. Why do I need a firewall? Doesn't Windows have a firewall?
A. You need a firewall to keep spyware programs from calling out and to keep bad guys from getting in (to your computer). Windows has a firewall, but it is a one way firewall. It won't stop spyware from calling out.

Q. If I have a firewall that keeps spyware programs from calling out, why do I need spyware removers?
A. A firewall will not keep spyware off your computer because many times spyware is installed by you. You may not realize that the new program you just installed has a spyware attached. If you don't read all of the user agreements while you are installing a program, you may be agreeing to install spyware. However, even if you do read the user agreements, some user agreements may not tell you there is spyware being installed. You can also get 'drive by spyware by going to a site that will install the spyware without your knowledge. There are other ways to get spyware as well. A firewall will keep hackers out, but will not prevent spyware from installing.
