sQusi, a free Web service for Windows users, ensures real-time protection against tracking cookies, scripts and files that advertisers use to track and profile you without your consent.

sQusi automatically and selectively blocks annoying ads, cookies, flash objects, IntelliTXT links, web beacons, script files and other file types from sites listed in its continuously updated database which is automatically disseminated to all users.

sQusi deletes non-essential cookies from Explorer, Firefox and Navigator with a single click. It also clears these files from the Explorer cache without deleting useful cached files from your favorite sites. sQusi stores no personal information, does not interfere with sites, and pages will usually load faster.

sQusi has a local database to maintain personal black/white lists that override global database entries. Version 1.07.3 fixes misc bugs.
