Much like human viruses, computer viruses run the gamut from the benign to the fatally destructive to the computers they infect. And just as with human viruses, prevention is better than cure. Prevention begins by stopping them in their tracks at the portals of contact. This is where a firewall can come in handy. 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. AVF 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. Spam is no longer harmless, silly, or simply annoying. It is increasingly harmful and we need to protect against it. How do these spammers get your email address? Each minute of each day, there are literally thousands upon thousands of spam email messages flooding inboxes the world over. Some of that email even goes out from what appears to be your very own email address! Where on earth do spammers get your email address? There are various ways - some are legitimate, and most are not. 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.
