We ask that you remove any P2P file sharing programs you have installed before we clean your computer.

Even the safest P2P file sharing programs that do not contain bundled spyware, still expose you to risks because of the very nature of the P2P file sharing process. By default, most P2P file sharing programs are configured to automatically launch at startup. They are also configured to allow other P2P users on the same network open access to a shared directory on your computer. The reason for this is simple, file sharing relies on its members giving and gaining unfettered access to computers across the P2P network. However, this practice can make you vulnerable to data and identity theft. Even if you change those risky default settings to a safer configuration, the act of downloading files from an anonymous source greatly increases your exposure to infection. That is because the files you are downloading may actually contain a disguised threat. Many very malicious worms and trojans, such as the Storm Worm, target and spread across P2P files sharing networks because of their known vulnerabilities.

Since we find the nature of P2P programs counter productive to restoring your PC to a healthy state, we ask that you remove P2P file sharing programs prior to our providing you with malware removal assistance.
