How Much Do You Know About Anti-spam Firewall?
Marco Maseko
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.
Windows XP, as well as the new Vista have a personal firewall built into the operating system that is by default turned on. Because it monitors and offers popup warnings many people turn it off, and leave themselves remarkably vulnerable to attack. The Windows firewall default of "on" should be maintained until and unless you find another software or hardware firewall to protect your system.
The good thing about firewall is the monitoring of the outgoing and incoming of programs through your internet connection. So you definitely monitor what's going on when working on the internet.

Email is the most common vehicle of choice for spreading viruses, and for hackers to get into your computer system. There is an increasing amount of this type of spam being mailed out of late. These small programs can be used in myriad harmful ways, including crashing your own system, crashing that of the parties you email or keystroke logging to gather your personal information.
Spam is no longer harmless, silly, or simply annoying. It is increasingly harmful and we need to protect against it.
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.
Some websites require you to register before you can place an order or access certain parts of the site. Not all these websites will be as protective of your email address as you may wish. Newsgroups are particularly notorious for exposing their users' email addresses to the spam gatherers. Most newsgroups do not take a great deal of care to hide the email of their users, and each and every email member email address is exposed and up for grabs by spammers. Some of the wbsites that aask you to register may also sell to spammers.
