Essay title: Block Potential Threats with a Solid Firewall Program

A couple of weeks ago, I gave you some of the top antivirus apps for your PC. The programs I listed were my picks for reliable free and shareware antivirus software that you could use right away.

Though having a good virus program is crucial to online safety, it's not enough to stop all intruders. Another extremely important line of defense is the software firewall. Some believe you need a hardware firewall (like as a function of your router, for example) to keep all intruders away from your system. But for most people (me included), a good software firewall offers plenty of protection against attacks and also against software on your hard drive that might be trying to contact "the mother ship" without your knowledge.
