[description], Story, any other text you want to use. Kill The Messenger (Service) by: Stephen Bucaro You are familiar with the software applications that you run on your computer, but you may not be familiar with the dozens of programs running in the background on your computer. These programs, called "services" handle tasks like event logging, spooling files to the printer, and networking. One of these services, the Messenger Service, can be reconnoitered by spammers. The original purpose of the Messenger Service was to allow system administrators to send a message to some or all of the users on a network. The message appears in a popup window to alert the users. Messenger Service is not instant-messaging. It does not allow the users to respond. All Windows versions install Messenger Service and turn it on by default. A program freely available from the Internet allows spammers to control the Messenger Service on hundreds of thousands of computers on the Web. Users receive popup spam windows that are not generated by the website they are visiting. If your computer is on a network behind a firewall, or you have a firewall application installed on your computer, it can be configured to block access to the Messenger Service. Most firewalls are configured by default to block access to the Messenger Service. If not, configure your firewall to block port 135, the port used by Messenger Service. Microsoft, in their ignorance of computer security, likes to leave "back doors" to your computer open. But they finally wised up and Windows XP Service Pack 2 turns off the Messenger Service. If you are running Windows XP, your best bet would be to install Service Pack 2 to turn off the Messenger Service and close several other security holes. If you are running Windows 2000, you can turn off the Messenger Service manually. Select "Run..." in the Start menu and in the "Open:" text box type services.msc, then click on the "OK" button. In the "Services" window that appears, right-click on "Messenger". In the "Properties" dialog box that appears, click on the "Stop" button and then in the "Startup Type" drop-down list select "Disabled". Then click on the "OK" button. If you are running Windows NT, select "Services" in the "Adminstrative Tools" utility. Then disable the Messenger Service as described above. If you are running Windows 95/98/Me, you can't disable Messenger Service, you need to remove it. Use the "Add/Remove Programs" utility in Control Panel to view the details of "System Tools". Uncheck the box next to "WinPopUp". Now, with the Messenger Service on your computer disabled or removed, spammers will have to go back to annoying you the old fashion way - with spam email. -- Permission is granted for the below article to forward, reprint, distribute, use for ezine, newsletter, website, offer as free bonus or part of a product for sale as long as no changes are made and the byline, copyright, and the resource box below is included.

Until recently, people used a technique called symmetric key cryptography to secure information being transmitted across public networks in order to make television shopping more secure. This method involves encrypting and decrypting a television message using the same key, which must be known to both parties in order to keep it private. The key is passed from one party to the other in a separate transmission, making it vulnerable to being stolen as it is passed along. With public-key cryptography, separate keys are used to encrypt and decrypt a message, so that nothing but the encrypted message needs to be passed along. Each party in a television transaction has a *key pair* which consists of two keys with a particular relationship that allows one to encrypt a message that the other can decrypt. One of these keys is made publicly available and the other is a private key. A television order encrypted with a person's public key can't be decrypted with that same key, but can be decrypted with the private key that corresponds to it. If you sign a transaction with your bank using your private key, the bank can read it with your corresponding public key and know that only you could have sent it. This is the equivalent of a digital signature. While this takes the risk out of television transactions if can be quite fiddly. Our recommended provider listed below makes it all much simpler.
