Hi YORGY, try this link:
winsock d/l"This Utility Restores (WinSock and TCP/IP) Registry Keys, that may become Corrupt after Removing the Host Program that Modified them."
Basically some viruses and ad-ware (New.net for example), modify your tcp/ip or internet connectivity settings. Removed said program can leave lingering entries and that may be causing problems. I've used this tool successfully for over a year now, just to make sure that network settings where restored.
If you're not sure that you are as clean as you need to be when it comes to network settings, etc. Just run it and make sure.
this quote is from a similar article by admin and makes perfect sense about what to do with it.
Hope this works for you
