What are the cookies?
The cookies are small pieces of information (text) that are created by Web sites that you are
visiting and are sent to your browser (Internet Explorer, Firefox or any other) along with the Web pages that you are
viewing. Some of these cookies are saved to your hard disk and
when you visit the same Web page again, your browser sends these cookies back to this Web site.
There are few general goals that are accomplished by the usage of cookies:
- To notify the Web site that you have visited it in the past. This information can be used to block some
one-time services (for example Web pools, one-time promotional services, etc.).
- To remember your user name and password so that you don't need to enter them each
time when you visit this Web site.
- To remember your personal information that is important to the Web site you are visiting.
It can be your name, personal preferences, advertising information, etc.
- To show you a different ad each time when you visit the site or similar ads to
ones that you have clicked in the past.
As you can see there are plenty of ways for cookies to threaten your privacy. Even if it seems that the purpose
of some cookies is innocent they still reveal the fact that you have visited this specific Web site.
Furthermore, the Web site can update the cookie every time you visit its pages, adding new usage information.
Cookies remain on your computer as long as their creator decides (from few days to many years). Some cookies are automatically deleted
when you close your browser (so called session cookies) but others can stay on your PC virtually forever.
You can use Mil Shield to delete the cookies while keeping some of them
(some decent and useful Web sites don't work without cookies).
As more and more people are becoming aware of the cookies, many Web sites started to use alternative methods to
identify their visitors - Flash cookies (local shared objects), UserData records, DOM storage. Each of these methods is
very similar to the ordinary cookies. Mil Shield cleans all these traces (selectively if you wish so) and it
also cleans the content of index.dat files, history, temporary Internet files and many other tracks.
