Want to make sure your Windows computer is set to defend against viruses and malicious code? Microsoft offers a fee online tool called Malware Prevention troubleshooter (again no points to MS for naming conventions) that will scan your computer and make sure Windows is patched and its security software is up-to-date.
Run the Microsoft Malware Prevention tool. It’s part of the Microsoft Fix It Center.
Then you have the option to have it scan your system and fix detected problems automatically, or if you like more control over your system, select the second option.
After the scan simply select the fixes to apply and click Next. For some fixes, like enabling UAC, a restart of your computer is required.
It also generates a detailed report that you can look through and save.
