In this post I am simply  doing an update to the ‘THELIST.txt’ file which is essentially a blacklist of web servers that are ad servers or have been found to be malicious. I have added more servers (mostly ad web servers). The file is accessible here:

http://zitstif.no-ip.org/THENEWLIST.txt
SHA1 (THENEWLIST.txt) = 02a2e93167f680a09f5047ef1b081483b680bfde

You can then download this file and append the output of ‘THENEWLIST.txt” to your hosts file.

For Microsoft Windows you will most likely have to do the following:

1.) iexplore http://zitstif.no-ip.org/THENEWLIST.txt
2.) Save the file to a location
3.) Run CMD.exe as an Administrator
4.) ‘cd’ to the directory where you saved ‘THENEWLIST.txt’
5.) Execute the following command: attrib -R C:\WINDOWS\system32\drivers\etc\hosts
6.) Then execute this command: type THENEWLIST.txt >> C:\WINDOWS\system32\drivers\etc\hosts
7.) Execute the following command: attrib +R C:\WINDOWS\system32\drivers\etc\hosts

For *nix hosts do:

1.) Gain root via: su or sudo -i
2.) chmod a+rw /etc/hosts
3.) printf “GET /THENEWLIST.txt HTTP/1.0\n\r\n” | nc -vv zitstif.no-ip.org 80 2>&1 | egrep -v ‘HTTP|Apache|Date:|ETag:|Accept-Ranges:|Content-|Connection:|Modified:|Connection’  >> /etc/hosts
4.) chmod a+r/etc/hosts && chmod a-w /etc/hosts

I hope this is useful to you. I think most people would like nearly ad free web browsing.  In addition to that, legitimate ad servers have been known to serve up malware:

So by using this file in tandem with the Adblock extension/plugin you can get for Firefox/Google-Chrome, you will be less annoyed by ads and not have to be too concerned about ads serving up malware for you.
