sQusi Tracking Blocker

sQusi is a free and useful web service which stops behavoral marketing companies from tracking you across the web and building profiles of your behavior through third and even sometimes first party tracking cookies, scripts and files.
Some experts describe these cookies, scripts and files as spyware while others call them stalkware. Either way, they are not good for you. They are placed on your computer without your permission and data that rightfully belongs to you, is sold to others without your consent.
sQusi uses a continuously updated database to automatically and selectively:
Block cookies, flash objects, web beacons, script files and other file types before they can be placed on your computer. These files either serve up annoying ads or in many cases, track your activity as you navigate from site to site.
Clean your Internet Explorer cache of these files without deleting useful cookies or cached files from your favorite sites.
sQusi has been tested and certified by experts at the authorized download sites (see Download) as being free of viruses, spyware, adware or anything evil.

How sQusi Works

The sQusi desktop client runs in the background on your computer. Each time you load a new web page in your browser, it checks the URLs received, and if any of them are listed in its database as to be blocked, it blocks them before they can be stored on your computer.
There are potentially thousands of URLs which can set these various cookies, files and scripts on your computer and it is virtually impossible for you as an individual to use your browser controls to block them. If you block all cookies, many sites will not function. If you block some well known URLs, they will change the address to get through.
The only way to stay one step ahead is to use a continuously and automatically updated database. sQusi has an auto-update feature that does this with no effort on your part. It regularly checks with sQusis servers for updates, downloads them and asks your permission to install them.

Compatibility

sQusi works on any computer that runs Windows 2000 or XP operating systems. It also works with any browser that runs on these systems including Internet Explorer, FireFox, Netscape Navigator and yes even Opera.

The sQusi Difference

sQusi will not interfere with the proper functioning of your favorite sites. What you will notice is a lot of beautiful open space on many of the pages you visit and in many instances the page may actually load faster because it does not have to load big ad files.
