BACKUP AND SECURITY
Microsoft has just released several important security updates, including a new version of its Malicious Software Removal Tool. In case you still don’t have your system set to automatic updates, go to the Windows Update Site.
Before you do, make a backup of your system state. A while ago I explained how to do it. I’ll go over the steps here again. They’ve changed slightly after installing Service Pack 2. I also urge you to make a backup of your system state every time you install new software, except for small applications by reliable companies, like the Google Toolbar.
You should also regularly backup your system state, as I have previously recommended, especially before cleaning your registry.
Click Start in the bottom left corner, hover your mouse on All Programs, Navigate to Accessories -> System Tools, then click on Backup.
