Today, the Internet is reminiscent of the wildest days of the Wild, Wild, West. Your stagecoach through the World Wide Web can be hijacked at any instant if you have no knight in firewall armor to ward off any viral intruders. When your computer is connected to the internet with no firewall running, it is vulnerable to attack from spammers, hackers and phishers.

An ideal firewall will hide the ports that a hacker might use to gain access to your PC and protect your home PC from attacks, as well as track those attempted entries and prohibit unauthorized access or output from your computer. Two-way firewalls are the best as they block the threats that are incoming OR outgoing, to prevent things such s virus, Trojans or malware from being installed without you knowing it.

You will need good anti-virus programs to go after any viruses that may inevitably bypass your firewall. It should be programmed to either quarantine or, preferably, destroy them. Last but certainly not least, it is essential to always keep your anti-viral and firewall programs up to date with the newest patches and security updates. Most viruses target your C: drive, so scan it daily. And never, ever open any unsolicited emails or the attachments that come with them.

An insidious tactic that the spammers employ is called “Phishing.” It involves the spammer sending out junk email that is specifically designed to look like it is from a reputable, legitimate source such as a reputable company like ebay or paypal. This spam utilizes the company’s logo and official graphics.

To understand just how big a problem spam has become, it will help to realize the sheer volume of unsolicited junk mail is sent out every day. More than 50% of all the trillions of email that is mailed out is spam. This spam clogs up and wastes bandwidth, especially with the recent advent of image-based spam. It places a huge strain on servers and wastes a huge amount of time and money to deliver millions upon millions of unsolicited emails to the inboxes of recipients.

How do spammers get your email address?

Typically, spammers will “harvest” email addresses from legitimate web sites, such as USENET groups, chat rooms, message boards, AOL profile pages and special interest group postings. These are sites you have visited and requested more information from, or corporate sites where you may have placed an order.

One way to defend against this is to make it more difficult for the spider to harvest your email. When you place your email address on a web site, remove the @ symbol and replace it with the word “at.” This makes it far more difficult for the spam harvester to gather your address, because it cannot be gathered mechanically; it can only by read by a human who is actually reading the site. Alternatively, you should display your email address as an image rather than as text.
