How to Block Internet Access of the Windows Programs without Using a Firewall ?

internet connection | How to Block Internet Access of the Windows Programs without Using a Firewall ? It is probably a month ago that I was testing some software that was taking so much time to start because at each startup it was needlessly trying to ring-back home to find an update (not sure that it was trying to find an update or trying to send some interesting info to the website). Nevertheless this process of checking for the update at each startup was not acceptable for me(unfortunately there was no option to disable the auto-update).  A simple solution was to just install a firewall and block inbound and outbound access of the selected application. However it was not an optimized solution to install a full-fledged firewall jut to deny access to the Network/Internet for an application. Although if you are using a firewall to tighten up your computer security then it is an entirely different matter. So I started to look around for a solution that could block net access to the user defined programs.

After some research I came up with the very useful tiny application called NoNet built exactly for this purpose to disable network connectivity for a desired application. It tackles the problem by injecting a piece of code in to the application that disables the winsock access and hence the network connectivity is disabled. To use it simply execute the NoNet executable and select a process from the process list that you want to deny access to and click the inject button and you are done.

Take a look as I have blocked access for the Internet Exploder 7:

If you want to start a program with no Internet activity then use the following syntax to execute the application (assuming that you want to deny access to the BuggyApp.exe):

“C:\NoNet\NoNet.exe C:\Program\BuggyApp.exe”

Please note that this hack will only work if the application in question is using the Winsock interface or more precisely WS2_32.DLL for network connectivity. Also don’t worry it will not damage your application by injecting code because the code is injected in memory only and when you restart the application it will be able to access the network normally as before.

    How safe is to use this, will it permanently block or something like that! :grin:

    Nirmal: Not at all the the blockage is just temporary for that session and after you restart that application it will be able to access the network normally as before . But you will have to restart the application however :smile:
    I someone wants to permanently block the access then he has to use the latter technique (command-line)
