I bought and installed DriveCleaner as certain sites seemed to pick up where I live and I thought this was evidence of an invasion of my PC. Norton AntiVirus advises me to delete it. Derek Parker
JS: Symantec, which owns Norton, says: "DriveCleaner is a misleading application, which gives exaggerated reports of security and privacy risks on a computer. The program then prompts the user to purchase a registered version of the software in order to remove the reported risks". All programs that do this are considered malware and should be removed.
Otherwise, lots of websites try to guess where you live using techniques known as geolocation. See http://www.dnsstuff.com/info/geolocation.htm
