Antivirus/Antispyware/Firewall uninstalls can occasionally cause internet connection problems.

The next time you uninstall the software, BEFORE you uninstall the software, please download the WinsockXPFix tool from the link below.. Then, after uninstalling the software, if you can't connect to the internet, try running the tool.
