Layered Service Providers (LSP) are small pieces of software that can be added or inserted into the Windows TCP/IP handler by other software. Data outward bound from your computer to a legitimate destination on the Internet can be intercepted by an LSP and sent somewhere other than where you intend it to go. LSP Explorer lets you view active LSP and Name Service Providers on your system, along with detailed information about each so you can determine whether or not they're legitimate. Access LSP Explorer can be run directly from the Add-ons menu. LSP Explorer works with all versions of Norman Ad-Aware.
