Cookies are small data packets containing information about your surfing habits on the Internet, which is then known to sites that know cookies on the Internet. Cookie is mainly used by advertising agencies to track population statistics and check whether a site attracts that consumer. Some websites also use cookies to store your recent account information. In this way, when you enter
Websites, such as Amazon.com, and when you have an account on the site, the site will immediately know who you are and automatically load your personal Parameter options. This is like Yahoo! How does such a site provide "myYahoo !" This private special service.

Companies such as Double-Click and NetGravity use cookies to compile information about online surfers, which is used by advertisers to deliver advertisements in a targeted manner. In the most popular search engine Yahoo! You can see an instance using this policy. When you connect to the site for the first time, it will display a seemingly random ad bar. After you enter a word, for example, "books for sale", to search for the ads, the ads suddenly start to boast Amazon.com.

How do I block cookies?

Is there any way to block cookies? Of course! You only need to use Microsoft Internet Explorer version 3.0 or later.

. IE provides an option to display a warning message when you receive a cookie from a site, and allows you to reject the cookie. You only need to check the menu and select the option ....... In the Options dialog box, click the Advanced tab. Scroll down the list box and set the always accept Cookies option to unselected. Then, select the prompt before receiving cookies.

For IE 5.0, select the Internet option in the tool menu ...... Select a security label and click in the Custom Level box. Scroll the slider to Cookies and change the options.

If you are using Netscape, you only need to select properties under the editing menu, and then select advanced in the displayed dialog box. Then, follow the same steps.

Reject Cookies

When IE notifies you that a cookie is being downloaded, you only need to click "no" when it asks you if you want to download it. Alternatively, you can disable all cookies so that the browser will no longer receive any cookies. The same is true in Netscape.

Once you turn on the cookie warning option, IE may be so frequent and even surprising about the possible cookie warnings. In fact, frequent warnings are annoying, but at least you will know when a site is spying on your information, rather than making all the activities happen in the background. What else can we do?

In addition to enabling the cookie warning option, you can also go to the Electronic Frontier Foundation (EFF) page to become one of them and register the request to try your best to prevent the advertising agency from using cookies. However, the best way to do this is to enable the cookie warning option and set up a browser to prevent intrusion. You will be surprised: How many Internet websites are hiring frauds for Madison Avenue.

Are there other options?

By searching for any file containing word cookies on a hard drive, you can delete the cookie file from your computer.

You can drag those files to the recycle bin or recycle bin. However, if you delete the cookie file, some settings may be lost, such as the password for accessing the site. In this case, when you visit these sites, IE will remind you to re-enter the password. To prevent some companies from placing new cookie files on your hardware, you can select an option in the browser, this option ensures that you are asked for your permission every time the outside world tries to place a cookie.

 

Another method is to use professional anti-virus software to scan and kill. For example, anti-virus software such as Cert 2009 and Spybot all have the function of killing and tracking cookies.
