Safe Browsing: Spyware, Adware & Popups
Is your computer's performance slowing down? Are you besieged by popups? Do you wonder where that new toolbar came from, or why your home page keeps changing? If you're experiencing any of these problems, chances are good that your computer has been infected with spyware. Although relatively recent in origin, the problem of spyware now has become epidemic among computers connected to the Internet. The good news is that with proper prevention, tools and monitoring, you can reduce the risks of spyware finding its way onto your computer.
What you should know about spyware, adware and pop-ups
Spyware is software that performs certain behaviors, such as filling your screen with advertising pop-ups (such programs are known as adware), collecting or transmitting personal information (through keystroke loggers), or changing the configuration of your computer, generally without your consent. Spyware can find its way onto your computer through free software downloads, malicious Web sites, clicking on pop-up ads, file transfers over instant messaging, or opening infected e-mail attachments. The results of spyware include decreased browsing speeds, system crashes, and compromised personal security.
