Anyone with access to your PC (either in person, or over the Internet) can install spyware programs on your system without your knowledge. Spyware programs are easy to install and virtually impossible to detect without anti-spyware software. Spyware programs can record your every move - gathering personal information about you; which web sites you visit, which ads you click on, the duration of your visits, your name, age, gender, credit card numbers, passwords, email addresses, online buying habits and more. Spyware threats have become commonplace, and have even outpaced viruses as the number one on-going danger facing on-line PC users today. The fact is you are increasingly vulnerable to privacy invasions unless you take steps to protect yourself and your computer assets. Webroot provides solutions that help you take control of your PC and your privacy. Spy Sweeper protects you with a sophisticated database of spyware definitions.
