While viruses still remain a threat to your computer, spyware and associated malware may actually be the biggest issue in today's Internet driven world. Many anti-virus programs have little in the way of spyware detection and removal tools, which is where Spybot Search & Destroy comes in. This free-ware program allows you to scan for and eliminate spyware and other related threats from your computer. Additionally, it can run in the background of your computer and constantly check for threats while you are surfing the Internet, and it also allows you to set up a schedule for scanning your computer to ensure that your PC stays spyware and malware free.

Spyware is usually not as noticeable as virus infections are because they usually do not cause specific parts of your computer to stop working, at least not immediately. However, over time, spyware can bog your computer down by installing other spyware and malware programs and using larger and larger amounts of your computer's processing power. Catching spyware with a program like Spybot Search & Destroy before it can begin to take hold of your computer is a huge part of keeping your computer working and running smoothly.

Spybot Search & Destroy is constantly updating its database of spyware to check for, ensuring that your computer is protected from the latest threats. Additionally, unlike with anti-virus programs, you can have more than one anti-spyware program on your computer. Therefore, even if you already have a software security suite installed on your PC, installing Spybot Search & Destroy will only improve the level of security on your computer.
