Special Feature: Warning: A New Scam
While this scam is not computer related, we like to warn our newsletter subscribers of any new cons and dangers from those preying on the unsuspecting. Please be wary of emails, phone calls or any other communication you receive where you are asked to provide any personal or financial information.
According to USTelecoms Crossroads Express July 17, 2006 issue, A new telephony-based version of Phishing dubbed Vishing has evolved from traditional Web-based phishing scams. The new technique has been used by criminals to collect details from credit cards, including the three-digit CVV security code, expiration date and account number. Vishing scams usually begin when the criminal gets a cheap and easily available VoIP number and then configures an automated dialing system to call people. When the call is answered, an automated recording alerts the person that his or her credit card has been compromised and the consumer should call a phone number immediately to correct the problem. The phone number is often a toll-free number with a spoofed caller ID of a legitimate financial company.
A computer-generated voice then instructs listeners to enter their 16-digit credit card number, expiration dates and verification codes. Once this information is entered, the visher has the information necessary to place fraudulent charges on the consumer's card.
Never call a telephone number provided in a phone call or an e-mail regarding possible security issues with a credit card or bank account. Only the phone number on the back of a credit card or bank statement is a valid number to discuss credit card account information.

Today's Topic: Insert and Overwrite
Question: When I go back to change or add text while typing, sometimes, instead of moving the existing text to the right to accommodate the new text, the existing text is replaced by the new text. It does not happen all the time. What causes this?
Answer:
You probably pressed the Insert key (Ins) on your keyboard. Normally, you can type characters between other characters and the existing text gets pushed to the right and/or down to the next line. If Overwrite mode is turned on, then any character typed will replace the character to the immediate right. If you see this happening, press the Insert key and you will return to Insert mode.
Most applications that provide text editing and inputting have two text entry modes available: insert and overwrite. In Insert mode, all new characters will be inserted at the current cursor position and the following characters will be pushed to the right. This is the default mode.
Overwrite mode specifies that all new characters will be inserted at the current cursor position and that following characters will overwritten, that is erased, as new characters fill their space.

Question: The Shut Down Process
What is the reason for closing all programs before shutting down the computer? What happens if this is not done?
Answer:
When you exit a program it will be able to close correctly. Many programs need to save information before they close. Some programs create temporary files and will delete them when you exit the program correctly.
In some programs, you can change the settings to do certain tasks when you exit the program. For example, in Outlook Express, the Deleted Items folder can be emptied when you close the program. In Internet Explorer, all temporary files can be removed when you exit.
To set Outlook Express to delete the contents of the Deleted Items folder, click Tools on the menu and then Options. Click the Maintenance tab at the top of the Options window. Click to place a checkmark next to Empty messages from the Deleted Items folder on exit. Click the OK button.
To remove all temporary files when you exit Internet Explorer, click Tools on the menu and then Internet Options. Click the Advanced tab at the top. In the Settings choices, scroll down to the Security section. Click to place a checkmark next to Empty Temporary Internet Files folder when browser is closed. Click the OK button.
