If it's just 1 website and hoping the ip-address doesn't change, you can add an entry in your host file pointing it to something else... That way it will always resolve to whatever you point it to.

Can you please give me instructions on how to locate the"host" file.  Is that the program file that I downloaded from this site?  If so, how do I add an entry to point somewhere else.  -  This has to do with a program I bought in 2005 and got three keys for three computers and now they are saying I need to purchase more keys.  Call their number but they appear to be out of business.

To open your host file follow these steps
Then, once you have it open, write something like this on a blank line without a # in front of it:

987.654.321.0 www.name_of_website.com

Open in new window


The number in front of the name of the website is a bogus IP-address, it will resolve to nothing, error out.

Save the file, reboot for good measure (not really necessary normally, but can't hurt).

Try to surf to the website you've entered in the host file, it should come up as not reachable.

browsers have parental controls that are either built in or can be downloaded for free, is that what you're looking for?

for example, chrome has https://chrome.google.com/webstore/detail/block-site/eiimnmioipafcokbfikbljfdeojpcgbh?hl=en

Unfortunately I use Firefox.  Not sure if they have something similar.

spravtek, I was doing fine up until Show hidden files, etc. - then, he says now navigate to the directory above and open the host file. -  I don't know which directory he is talking about.  It's not listed in the view mode and I noticed his example host file is dated in 2009.  Can you help me out please? Thanks.

spravtek, Making progress. I think he was talking about the path he showed earlier; e.g.;
%systemroot%\system32\drivers\etc.  -  problem for me is he didn't complete the full path and I don't know what to add to it.

One more thing, is it possible that I could find the key or whatever you call it that let's them know that I have activated their program and delete it.  Would that be a better way to do it?  I am attaching a pic of what I get when I bootup and it's very annoying because they kill the program at that point.  I shouldn't even be having this problem because I paid for all three keys.

Messing with keys and programs is not the thing to start with, will cause some headaches.

That said, just open your notepad with administrator rights, click file > open, browse to C:\windows\system32\driver\etc\hosts  (no extension)

Only if you open and run notepad with administrator rights will you be able to save your changes.

spravtek, I'm going to heed your advice and stay away from this.  I am certainly not qualified to get into stuff like that.  One more question, can the program be modified so that it does not send a cookie to the website when it's activated or is that just as technical?  Lastly, I am learning to use AutoHot keys.  Can I write a script that would block them from access?  I really appreciate your time and effort.

Adjusting your hosts file is nothing to worry about, that is something you can do without any risks to your machine, but messing with keys and programs or trying to stop cookies is another thing ... That's quite technical.

Now, if you change the hosts file, the program will not be able to resolve the name of the host (if the hostname is the same as the website, it might go to a different url)... But I wonder, if it can't connect to the website, will the program still run? Won't it just shut down?

You are probably right.  Seems like thein data base would be looking for a confirmation before I could proceed.  What about the idea of writing a script for AHK that would block them access to my computer?

Same thing, as long as the software doesn't get confirmation from the server that the license is ok, it probably will not start ... You could try to block the access with the firewall ... A script seems like a lot of work.

We gave it our best shot.  I'm going to continue to try and contact the vendor and see if we can resolve this.  Since I can't get anything but a message when I call and they won't return my call I think they may be out of business.  One last comment.  Are adons for Firefox as suggested by Big Monty safe to use?

Most add-ons in Firefox are safe, especially through the Firefox market ... Just be aware of add-ons that come from fishy sites...

Good luck!
