Any Security Software Installed?:
If there is Security Software installed, you may be connected to a VPN. If so, uninstall it. Use the correct Uninstaller for it. Get it from none other than the manufacturer. Getting it elsewhere may result in malware (Malicious Software) or spyware being installed.
