Microsoft Security Essentials and Windows Defender

Tuesday, December 14th, 2010 by | Filed Under: Security Help, Uncategorized

Robert, from Stockton California asks:

I installed Microsoft Security Essentials, which shut off Windows Defender, and it won’t turn back on. Which one is the best protection?

Microsoft Security Essentials and Windows Defender are both anti-malware software that are made by Microsoft.

What is the Difference Between Microsoft Security Essentials and Windows Defender?

Windows Defender is designed to protect your computer from Spyware only, which is a type of malware that causes irritating advertisements and lower system performance. It is not made to protect your computer from the other types of malware such as viruses, Trojans, rootkits, and rogue security software. On the other hand, Microsoft Security Essentials is designed to detect and remove most types of malware.

Is Microsoft Security Essentials better than Windows Defender?

Microsoft Security Essentials is not designed to permanently replace Windows Defender. However, it does provide more enhanced security features than Windows Defender. Therefore, you do not need to run Windows Defender when you have Microsoft Security Essentials. In most cases, though, it is recommended to use Microsoft Security Essentials instead.

Does Microsoft Security Essentials Automatically Disable Windows Defender?

Microsoft Security Essentials is programmed to disable Windows Defender. However, this does not happen in some cases. If this does not happen, you should disable Windows Defender manually. If you let both of these programs run simultaneously, you might experience some incompatibility problems.

How to Manually Disable Windows Defender

Step 1

Go to the Start menu. Click All Programs and open Windows Defender.



Step 2

Go to Tools and click Options. Next, disable real-time protection and Automatic scanning.


Thanks for the question, Robert.

I hope this helps.
