Learn how to safely cruise the Internet to avoid viruses

(Continued)

NORMAN —

However, if the link’s address says something else, like xrdmnhack.ru (“.ru” indicates a Russian website), you have good reason to be suspicious. This link-displaying “look before you click” feature also works in many email programs, such as Outlook.

Another way of being warned about malicious websites is through some type of website filtering tool. These tools will give you a warning notice if you attempt to visit a dangerous site.

The Firefox browser has a website filtering tool built in, being based on security scans done by Google. To see if this feature is enabled, go to Tools/Options/Security. There should be a check mark in the box that says “Block reported attack sites” and “Block reported Web forgeries.” If you try to visit a bad website, a maroon-colored warning window will open up saying, “Reported attack site.” Click on the “Get me out of here” button and you’ll be safe.

Internet Explorer has a similar, but less trustworthy tool, based on website scans done by Microsoft; all the more reason to ditch Internet Explorer in favor of Firefox.

Another website filtering tool I recommend adding to your browser is called Web of Trust (mywot.com). The combination of Web of Trust and your browser’s built-in filtering is pretty effective. For more information, read my 6-14-09 column titled “Who do you trust?” on my website.

However, none of these website filtering tools are perfect. Your most effective tool against website attacks is still common sense. A recent study by Symantec shows that 44 percent of the search terms that led people to dangerous websites were for “adult” entertainment. The moral of the story? Stop searching for porn websites.

Other dangerous activities include downloading bootleg songs and videos. If you find yourself trapped in a looping website attack, don’t click on anything. Instead, use the control-alt-delete method that I describe in my 3-7-10 column titled “A scareware epidemic.”

On the other hand, many otherwise legitimate websites are dangerously infected, so, use your tools, use your brain and have fun practicing safe surfing.
