The best internet privacy software isn't a choice anymore, it's a necessity. With new threats to computer security and data integrity being a regular feature of the electronic age, a host of products that promise to detect, protect, and dis-infect are being marketed to online consumers. We all need the best internet privacy software to maintain our security and protect our right to privacy.

Intrusion-detection systems, firewalls and anti-virus software are critical to online security, but the Federal Trade Commission, the nation's consumer protection agency, says computer users -- from grade school kids to grandparents -- need to know exactly why they need online security products and what they're buying. First off, here's why you need the best internet privacy software. Why you need to permanently shred all of your unnecessary files.

*Why the Need

Computers "talk" to each other over the Internet by sending data through their communications ports. If a port is open, it "listens" for communications from the Internet. A computer has thousands of ports: which ones are open depends on the software the computer is running. Hackers can "eavesdrop" or scan the ports to determine which are open and vulnerable to unauthorized access.

*Detection

An intrusion detection system (IDS) monitors incoming Internet traffic, much like a security camera "watches" your front door to see who might be trying to come in. When the IDS detects a suspicious pattern, it sends an alert (and creates a record) that an intruder may be trying to break in to your computer. Some IDS alerts -- but not all -- show a pop-up message on your screen. An IDS alone cannot prevent an unauthorized entry into your computer; only a firewall and the best internet privacy software can help us there.

*Protection

Firewalls block a hackers' access to your computer by creating a barrier -- like a wall -- between your ports and the Internet that allows you to control the data that comes and goes through your ports. Your firewall protects your ports even if you don't have an IDS. Sometimes a firewall is bundled with an IDS. If not, and if you want an IDS, be sure it's compatible with your firewall.

*Dis-infection

Anti-virus software detects and deletes viruses that are in your computer. Viruses often attach themselves to your computer through email attachments and floppy disks. That means a firewall can't catch them. Similarly, an IDS won't alert you when a virus is attacking your computer. Look for anti-virus software that recognizes current viruses, as well as older ones; that can effectively reverse the damage; and that updates automatically.

*On a Personal Level: Everything we do, everywhere we go or have been on our computers, can be seen by bosses, spouses, government, anybody that's computer savvy. To maintain our privacy, good software can erase all internet activity. Our PC hard drives keep "footprints" on them, tracks that aren't erased by just deleting history, caches, cookies, temp. files, etc. Among all the online consumers choices in security products, it is critical to install trusted software that erases all your internet activity.
