AutoComplete Can Be Auto Fraud
The AutoComplete option in Windows Explorer can lead to automatic fraud. AutoComplete remembers login names, passwords and even credit card numbers. This leaves your computer vulnerable to a number of problems:
1- Other computer users besides you can access your bank accounts or email.
2- Other computer users besides you can use your credit card number, including your children, to order drugs, weapons, or anything else.
3- Windows Explorer currently has a security flaw that allows this information to be hacked using virus code that exists on tens of thousands of websites.
Turn AutoComplete off. Go to Tools > Internet Options > Content > AutoComplete to disable this feature. AutoComplete is a bad idea in any browser. If you have problems remembering your passwords, store them in a password protected location other than your browser.
