A couple of nice apps that could restore connectivity

Originally read about them here: http://weblogs.asp.net/cfranklin/archive/2005/08/27/423798.aspx ----------------------------- WinSockFix description found here
WinSockFix offers a last resort if your Internet connectivity has been corrupted due to invalid or removed registry entries. It can often cure the problem of lost connections after the removal of Adware components or improper uninstall of firewall applications or other tools that modify the XP network and Winsock settings. If you encounter connection problems after removing network related software, Adware or after registry clean-up; and all other ways fail, then give WinSock XP Fix a try. It can create a registry backup of your current settings, so it is fairly safe to use. Note: Be sure to read the "Info" before running this software. ------------------------------------------ HijackThis HijackThis lists the contents of key areas of the Registry and hard drive--areas that are used by both legitimate programmers and hijackers. The program is continually updated to detect and remove new hijacks. It does not target specific programs and URLs, only the methods used by hijackers to force you onto their sites. As a result, false positives are imminent, and unless you're sure about what you're doing, you always should consult with knowledgable folks before deleting anything.
