Most internet sites use Google Analytics, which downloads an enormous pile of javascript on your browser, which systematically probes your system for one thousand and one privacy holes and weaknesses and reports back to Google Analytics, which then shares some of their spy data with the site that surreptitiously downloaded their enormous pile of hostile spy attack code onto your computer.
Modify your hosts file to include the following lines:
0.0.0.0 google-analytics.com 0.0.0.0 www.google-analytics.com 0.0.0.0 ssl.google-analytics.com
On Linux, your hosts file is found under /etc
On windows found under %windir%\system32\drivers\etc
