Ok, so I did a search with the SD search enging to find such black lists, but nothing turned up for me. So, now I am putting it to the crowd. I am looking for a list of IP’s and websites that are known to put spyware on people’s computers. It is my intention to put this list in my router so that nothing from these websites can infiltrate my computer later on. Thats about all Ficer67 ---

Sorry. Since such programs often have political biases, these companies would rather not release their black-list for fear of exposing their bias. Furthermore - Wait, I read this too fast, and thought you were talkiing about software that blocks certain pages. Whoops. Here is a real answer. [http://blocklist.org/](http://blocklist.org/) ---

[http://blocklist.org/](http://blocklist.org/) I don’t understand that answer. Is the suggestion to run PeerGuardian 2 and load those files? Does anyone just publish a list of evil hosts to append to the hosts file (similar to ad-lists)? ---

I should have Googled first. Looks like the ad-lists are including evil hosts also (e.g. [mvps](http://www.mvps.org/winhelp2002/hosts.htm)) ---

You might be looking for something like this: [http://www.bluetack.co.uk/modules.php?name=Content&pa=showpage&pid=1](http://www.bluetack.co.uk/modules.php?name=Content&pa=showpage&pid=1) It is a software that manages different black lists (the developers of the software maintain a lot of different lists, depending on category, but you can edit/import you own too). The black lists can then be exported to a variety of widely used Firewalls and I guess you could export it to just a list of IPs for inputting into your router. ---

I have a link for [this great page about using your hosts file to block bad web pages](http://www.mvps.org/winhelp2002/hosts.htm). From that page: > [@](#): > > The Hosts file contains the mappings of IP addresses to host names. This file is loaded into memory (cache) at startup, then Windows checks the Hosts file before it queries any DNS servers, which enables it to override addresses in the DNS. This prevents access to the listed sites by redirecting any connection attempts back to the local machine. Another feature of the HOSTS file is it’s ability to block other applications from connecting to the Internet, providing the entry exists. > > You can use a HOSTS file to block ads, banners, 3rd party Cookies, 3rd party page counters, web bugs, and even most hijackers. This is accomplished by blocking the Server that supplies these little gems. Example - the following entry 127.0.0.1 [ad.doubleclick.net](http://ad.doubleclick.net) blocks all files supplied by that DoubleClick Server to the web page you are viewing. This also prevents the server from tracking your movements. Replacing the (normally empty) hosts file with the one from that page works really well on my Windows XP and Windows 98 machines at home, but not at all on my Windows 2000 machine at work (probably because of the unusual network set-up there). ---

> [@CaveMike](#): > > I don’t understand that answer. Is the suggestion to run PeerGuardian 2 and load those files? Um, more like run the program, period, but yes. I maintain that PG2 is a superior product for newbies, rather then configuring lists. Of course, it sounds like you are look for something more indeph, but I couldn’t tell from the OP, and still, it’s a great program. Please, for the love of Zod, people, express something about your knowledge of the tech in the OP. It would really help, I think. I basic description of your OS, and failed solutions would do it, I think. Sorry for the junior modding, but it is the way I feel. All will kneel before Zod! ---
