Description
Your McAfee Real-Time Scanning service stops functioning unexpectedly and your protection status changes to Red. An error similar to the one below will be displayed in McAfee SecurityCenter:




Solution
Perform each of the steps below to enable Real-Time Scanning in the SecurityCenter.

If Real-Time Scanning will not start or becomes disabled again, continue to the next step.


Step 1 - Enable Real-Time Scanning in McAfee SecurityCenter

1. Double-click the M icon in your taskbar. 
2. Click Navigation and select the Real-Time Scanning link.
3. Click Turn On.
   
   NOTE: The Turn On button will be available only when Real-Time Scanning is off.
    
4. Return to the main SecurityCenter page and verify that Real-Time Scanning remains on.
5. Close McAfee SecurityCenter.

If your status still shows that you are unprotected, continue to Step 2.


Step 2 - Run McAfee Virtual Technician (MVT)

McAfee Virtual Technician (MVT) is an automated self-healing tool that can diagnose and fix many problems related to your McAfee product.

Go to http://mvt.mcafee.com and follow the prompts to install and run MVT.  If MVT discovers any problems, allow it to repair those problems and attempt to enable Real-Time Scanning again.

If your status still shows that you are not protected, continue to Step 3.


Step 3 - Download and run the oas-disabled-fix.cmd utility

1. Download and save the utility from the link below to your desktop:
   
   http://download.mcafee.com/products/licensed/cust_support_patches/oas-disabled-fix.cmd
   
    
2. Double-click the oas-disabled-fix.cmd tool.
   
   NOTE: Windows Vista and 7 users should right-click oas-disabled-fix.cmd and select Run as Administrator.
   
   If you receive the error StopService: Unable to open service McShield via SCM (5), press CTRL+C to terminate the process.  You will be prompted to terminate the batch job. Type Y and press ENTER. Run the oas-disabled-fix utility again.
   
    
3. Restart your computer and ensure that McAfee Security Center shows that Real-Time Scanning is enabled.

If your status still shows that you are not protected, continue to Step 4.


Step 4 - Check for non-McAfee security software

Other security software may cause a conflict with your McAfee products. For instructions on how to remove incompatible third-party applications and a list of many incompatible products, see TS100914.

After you have removed any incompatible software, enable Real-Time Scanning in McAfee Security Center.


If your status still shows that you are not protected, continue to Step 5.


Step 5 - Remove and reinstall your McAfee software

For details on removing and reinstalling your McAfee software, follow the instructions in FAQ article TS100507.

If Real-Time Scanning is still disabled, contact McAfee Technical Support. Go to https://service.mcafee.com and select Technical Support.





Additional InformationRunning a System Restore on your computer can cause the Real-Time Scanner to become disabled. System Restore attempts to return your computer to a stable restore point from the past, but that restore point might have been created before critical updates were installed.
