Step 2: Adjusting your security level for macros

Macros are handy little shortcuts that you can use to store keystrokes and automate common tasks. Sometimes hackers use this same convenience to create macro viruses that can seriously damage your computer.

To adjust macro security in Word, Excel, PowerPoint, or another Office document:

1.	On the Tools menu, click Options. If you don't see Options, wait a couple of seconds for the menu to drop down completely. It may be hidden.
2.	Click the Security tab.
3.	Under Macro Security, click Macro Security.
4.	Click the Security Level tab, and then select the security level you want to use. Tip: We recommend setting your macro security level to "high," and clearing the "Trust all installed add-ins and templates" check box (that is, make sure it's not checked).

Step 3: Use Microsoft Update to update your Microsoft software

A key feature of Microsoft Update is Windows Automatic Update, which automatically installs high-priority updates that are critical to the security and reliability of your computer. Without these updates, your computer is more vulnerable to attack from cyber crooks and malicious software.
