I talked about NET SEND spam in my previous blog. After that, I found this page become the first item in Google for net send spam. Many visitors hit this page via Google. I believe I share the responsibility to publish something that is helpful for the visitors to prevent this kind of spam.
Messenger service is dangerous
If you keep your Messenger service running, anyone can send you a message and it will pop up on your screen. Even the simplest program ever can drive you mad. Create a file named “NetSendSpam.bat” with the following three lines.
net send 127.0.0.1 How are you
It keeps sending the same message to you again and again. You will face endless message box stating “How are you.” – Please do not try this script to anybody except yourself. To send spam is as easy as picking up a stone and breaking the store window, but everyone in this world should realize their responsibility and don’t abuse others.
Easiest way – turn off Messenger service
The easist way to stop receiving this kind of message is to turn off Windows Messenger service. If you are running Windows XP, following these steps:
- Click Start button on your toolbar.
- Click Run…
- Enter “Services.msc” (without quotation marks) and click OK.
- Browse the list till you find “Messenger” in Name column
- Right click and click “Stop” on the pop up menu.
That is not all. If you don’t want the service to start the next time you start your computer, continue with the following steps:
- Double click it. The Messenger Properties (Local Computer) dialog box comes out.
- Choose “Disable” in “Startup type” drop down box.
- Click OK.
Update The equivalant method
Thanks to Docslax for pointing this out. There is another equivalant way to do this in Windows.
- Start -> Run -> cmd.exe
- Then type the following “net stop messenger” after which you’ll see “messenger service is stopping”.
To start it again for any reason open the command prompt again (Start -> Run -> cmd.exe) and type “net start messenger”
Now you can be assured that your world will become silent. No one can send you NET SEND SPAM again.
But wait, that is all
Please note: some alert services and system services like printing, rely on this service to function.
However, as I understand, there are two kinds of people using computers ?those in company or those at home. I believe most people surfer from NET SEND SPAM is home users connecting to DSL or Dial-up. For cooperate users, they need printers and file sharing functions, but they are more likely to be protected by corporate firewall. So my suggestion is, anyone who surfers from NET SEND SPAM to turn off the service using the step listed above.
You can also fight back
If you are using Windows XP or you have personal firewall product, it is even better to enable them. But enabling a firewall, you not only eliminate the chance to be attached by spam, you can also get the IP address of the spammer and you can fight back. I will talk more about this in my future blog.
