Computer shuts down every time I try to run a McAfee Full Scan.

My computer shuts down during a McAfee Full Scan at 28-30% completion, and then is difficult to reboot. This only occurs during the Full Scan (Quick Scan is fine, and detects nothing), and also occurs when I try running it in Safe Mode. I contacted McAfee Technical Support. A technician took remote access of my computer and said a Windows file is preventing the scan from completing, and suggested I contact Microsoft. I have no idea what file it is choking on, though, because the computer shuts down too fast to see which one it is. Please advise.

 As you do not have the file name that is supposedly blocking it, can you get the file name from McAfee to help us help you.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Otherwise, you will have to follow these steps:

 

First thing to try is a System Restore to before the problem:

 

 

Do System Restore in Safe Mode, if unable to do it in Normal Mode.

 

Try tapping F8 at startup, and from the list of startup selections, select Safe Mode by using UP Arrow Key to go there > then hit Enter.

Try a System Restore once there, to pick a Restore Point before your problem..

Click Start > Programs > Accessories > System Tools > System Restore > pick a different time > Next > etc

If the above does not fix the problem, follow these steps to improve performance and resolve the issue:

 

 

Go to your Laptop/Computer Manufacturer's website > Drivers and Downloads Section > Key in your Model number > Look for latest Vista Drivers for it > Download/install them.

Run the Vista System File Checker Tool:

http://www.tech-recipes.com/rx/2231/vista_run_system_file_checker/


1. Open a Command Window in Administrator mode:

* clickStart
* click All Programs, thenAccessories
* right click on the Command Prompt option,
* on the drop down menu which appears, click on the Run as Administratoroption.

 

* If you haven’t disabled User Account Control (and you shouldn’t!) you will be asked for authorisation. Click the Continue button if you are the administrator or insert the administrator password.

2. Start the System File Checker

* In the Command Prompt window, type:sfc /scannow,
* press Enter.
* You’ll see “the system scan will begin”.

The scan may take some time and windows will repair/replace any corrupt or missing files. You will be asked to insert your Vista DVD if it’s needed.

Close the Command Prompt Window when the job is finished.

One caveat: you need a Windows DVD to enable SFC to make more than minor repairs.

If SFC finds serious errors it can not fix, you may have to do a Vista Repair Upgrade Install.

If you do not have a Microsoft Vista DVD, borrow one from a friend.
