Each of these mechanisms has its drawbacks as well as its advantages. The application gateway is considered to be a more advanced and secure firewall mechanism than the other three, but it uses more resources (memory and processor power) and can be slower. Packet filtering is generally faster and easier to implement, but is susceptible to attack from users faking their source IP address (IP spoofing)or source port to trick your firewall into thinking that the traffic should be allowed through.

Free antivirus software may be the only option for those on a limited budget. The question, of course, is how well free antivirus software protects your PC, how easy is it to use, and if something goes wrong will you be left out in the cold? The answers may surprise you. This review looks at three free antivirus solutions: AntiVir PersonalEdition Classic, AVAST 4 Home Edition, and AVG Free Edition.

Sporting a traditional interface that's easy to navigate, AntiVir PersonalEdition Classic provides pre-configured scan tasks for scanning local drives, local hard disks, removal drives, the Windows System and My Documents folders, as well as manual scanning options for scanning items listed under My Computer. Right-click scans can be performed on individual files and folders in Explorer or on the desktop. Additionally, files can be dragged and dropped into the AntiVir console for quick scanning.

AVAST 4 Home Edition installs an interface that could be described as either clever or cumbersome, depending on your point of view. Borrowing on the WinAmp-style skins, the look can be changed by downloading a new skin from the vendor's website. Regardless of the skin, however, it's less than intuitive for those who prefer a standard Windows interface with easy-to-browse menus. AVAST 4 Home Edition is the only one of the free scanners to offer scans on bootup. This can greatly increase the chance of removing stubborn infectors, particularly those that use resuscitators to thwart removal attempts. (Each of the free scanners can be run in Safe Mode, however).

Like any scanner we feature in our reviews, AVG has been certified to remove 100% of in-the-wild viruses - but results with zoo viruses are a low 81% and those same tests resulted in 11 false positives (detection of viruses in non-infected, legitimate files). Despite these drawbacks, AVG Free Edition has a long list of admirers who will be quick to point out that tests reflect a snapshot in time and may not always be indicative of future or past performance.

An online virus scanner should never be considered a substitute for an installed antivirus scanner. But if you suspect your installed antivirus is missing a threat or you simply want a second opinion, an online scanner can be a valuable adjunct to security. Each of the following online scanners are considered best-of-breed and can offer important adjunct protection.

When I was a kid, my mom used to put a baking soda paste on bee stings and bug bites. I'm not sure it really helped that much, but psychologically it made me feel alot better. McAfee's AVERT labs has released a new tool, Stinger, that takes the sting out of many popular viruses and it's definitely much more than a 'feel good' fix. At a time when virus writers specifically target antivirus software, disabling its protective shields and leaving systems difficult to disinfect, Stinger is a must have in your arsenal. Best of all, Stinger is free - consider it a philanthropic remedy to cure today's most common viruses.
