Summary: There are ways to block URLs in IE, but doing so will block them from all other programs as well.

Is there a way to block certain URL's in IE? |
Actually, there is, yes. But when you do it, you'll be blocking them in IE and any other program that might attempt to access them.
Interestingly enough, it's the same technique that some viruses use to block you from getting to anti-virus sites.
•
Normally Windows uses what's called DNS to map a domain name, such as "microsoft.com" to an IP address, like "207.46.130.108". It's easier for you and me to remember domain names, and this also allows the domain name owners to change their internet addresses at will.
The "hosts" file is a plain text file that can contain overrides to DNS. In it you can hard-code the IP addresses that domain names will map to. Normally, it's not used at all, but it's a great opportunity to block access to domains you don't want accidental access to.
The hosts file is typically found in "c:\windows\system32\drivers\etc\hosts". You may need to change the file's read-only attribute so that you can make changes. Open it in notepad.
You should notice an entry like this:
127.0.0.1 localhostThat defines the IP address of "localhost" to be 127.0.0.1, which by definition is your own machine.
To block a site, just add a similar entry to the end of the file. For example:
127.0.0.1 www.badsite.comNow "www.badsite.com" is mapped to your machine. Since you're probably not running a web server, any attempt to visit that site using a browser will fail. In fact, ANY attempt to use "www.badsite.com" will get directed to your own machine and will typically fail.
The only caveat is that addresses are often cached by the software. That means you may need to exit all instances of your browser, for example, before the blockage becomes apparent. In the worst case, reboot, and it should take effect.
By the way, if you open the hosts file and find a long list of what look like anti-virus site domains, you've been infected by a virus and probably want to scan as soon as possible. And feel free to delete those entries from the file.

whenever i try to save the file it windows says it cannot create the file, and to make sure the path and file name are correct, i checked, both were.
i also checked to make sure that it wasnt read only, and it was not, so im not sure of the problem.
help?
Posted by: samma at August 4, 2009 1:25 AMLeo is perfectly correct all he has said here. But who are saying its not working make sure you typed 127.0.0.1 (spance here) www.badsitename.com.
Without space it won't work.
And the message it cannot create the file, and to make sure the path and file name are correct: is shown because the file hosts is being accessed by another process (may be your antivirus). If so then first disable antivirus then try to change the file again. Hope, you'll able to do this time.
But Leo I need a little bit more expand with that. Suppose I want to redirect all subdomains of the site badsitename.com. e.g, blog.badsitename.com, www.badsitename.com. webmail.badsite.com etc. Then without writing all these can I do this just by this kind of trick:
127.0.0.1 *.badsitename.com
Another issue: If someone tries with the ip address of the badsitename.com he can easily enter the site because we are redirecting during domain name to ip conversion processing. What is solution if I also want to redirect if someone tries with the ip address of the site.
Thanks leo very much.
Thanks Leo.
For sites that have dedicated servers, there's no way to block direct-IP address. The good news is that many sites are on shared hosting, which means that an IP address alone is not enough. More here: Why doesn't accessing a site by its IP address work?

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost
here my file but I don't see the site that I want to block.
Also this started because whenever I try and goto a particular site it loads it for a second and then redirects me here which I am hoping if I block it will stop this nasty little redirection. Any other assistance would be gratefully accepted. Thanks
