LSP-Fix is a free utility to repair Winsock 2 settings a specific type of problem associated with certain Internet software. This type of software is known as a Layered Service Provider or LSP, a piece of software that can be inserted into the Windows TCP/IP handler like a link in a chain. However, due to bugs in the LSP software or deletion of the software, this chain can get broken, rendering the user unable to access the Internet.
Unfortunately, this type of software is sometimes quietly installed by unrelated software such as file-sharing programs, malware, trojans and others. In fact, in many cases, the user does not know of its existance until something goes wrong, and he/she can no longer access Web sites. LSP-Fix repairs the Winsock LSP chain by removing the entries left behind when LSP software is removed by hand (or when errors in the software itself break the LSP chain), and removing any gaps in the chain.
Note: LSP-Fix is not a malware removal utility and does not target specific products. LSP-Fix does not delete any files.
