I Spy

In the real world, video cameras capture our every move at ATMs, convenience stores and the mall. Now, at startling speed, we're being spied on when we surf the Net. That's because stealth software programs can be secretly installed on your computer. These programs, known as spyware, record what you do and send your private information to…well, who knows where? And it's being done without your knowledge or permission.

Spyware is the name given to a wide and growing range of software programs designed to steal your personal information. This data is then sent to advertisers or possibly criminals.

Some spyware records your keystrokes. Why would this interest thieves? Because when you logon to your financial accounts, they can figure out your passwords by analyzing what you typed. The next thing you know, all your money has been transferred out of your account.

Other types of spyware may redirect you to unsavory adult websites. Another type of spyware, called adware, is responsible for those annoying pop-up windows.

Spyware is typically downloaded from the Internet without your consent. It can take the form of a virus or be part of a "free" program that you download, such as pier-to-pier file sharing programs. Once it's installed on your computer, it secretly gathers information and transmits it.

Start by finding out if your computer has been infected. If it begins to run slowly or you are suddenly barraged by pop-ups, even if you're not on the Web, the chances are that it is. Some ISPs, like AOL, offer spyware screening as part of your subscription, but it's still a good idea to scan you computer once a week with anti-spyware software. You can get spyware removal software at Download.com. One program we like is Spybot Search & Destroy.

Next, if spyware has infiltrated your computer, remove it as quickly as possible. Anti-spyware software scans your drives and shows you which programs are installed. You can then select the ones you want to remove. Be aware that by removing certain spyware software, it might disable the program that originally installed it on your computer.
