how to block idm in hosts file

There is a simple way to do it.The hosts file can be found in the folder …C:\WINDOWS\system32\drivers\etc … hosts.Usually used to redirect DNS requests this file can also be used to hardwire break a connection request by directing the request to the loopback address instead …ie 127.0.0.1Below is a simple set of addresses that I use in the hosts file ... which insures that these requests never make it out (into the www) … because despite having blocked the application via some personal internal firewall … the request / lookups were still being made … until now.Use most any basic Windows text editor to modify the file.

Hello, I find this information in a website.
You can see whether it can help you:
When you surf to a site, Windows automatically checks to see if the address is located in the Hosts file. The number 127.0.0.1 is the "loop back" IP address of your own computer, so Windows skips the link to the site (media.fastclick.net) and moves on. The ad server can't open its window, so it can't load any programs, spyware, or cookie files either.

You can open the Hosts file in Notepad and edit the entries so the sites you want to avoid are blocked. In Windows XP, the file is located in the C:\Windows\System32\Drivers\Etc folder. You can learn much more about the Hosts file at this page: http://www.mvps.org/winhelp2002/hosts.htm

In fact, this page also has a downloadable Hosts file you can use just by copying it into the Etc folder. Or you can view the file to see what evil parasitic sites you want to avoid. The downloadable Hosts file is 318K and the page has a note that says Hosts files that are larger than about 135K can actually slow down your computer.

As a compromise, I just copied out the lines for the ad networks I knew about from the downloaded file into my Hosts file. Over time, I may find more annoying sites, and I'll just add those entries into the file. Having the download as a reference is really handy, since it has comments that explain what some of the bad sites are up to.
