WClean is a utility to help network administrators in eliminating programs such as P2P programs and chat programs. Most P2P applications are designed by default to use whatever bandwidth is available. Many Companies have witnessed outbound utilization levels of nearly 100% 24 X 7. Many networks can become so congested and unstable that users cannot load simple web pages. Many new file sharing applications are able to swap port numbers therefore it is difficult in blocking the application. WClean is therefore crucial to a network or even a workstation when shutting down these applications. WClean has the ability to shut down setups for kazaa, msn messenger and many other applications.
