On XP, Vista and Windows 7 many people have found that the removal process including that used by Windows Update does not remove one important registry key if "Microsoft Security Essentials Update Package" is present. The registry key to remove depends on the version of MSE, not the version of Windows.

At the time of writing the batch file above does not remove the offending registry key. One of many threads which mention this look for post by fos4X , though I originally found this key mentioned in a post by Stephen Boots. You may have noticed that 1st and 3rd key are already in the script but 2nd one is not. I have made a suggestion to add 2nd one also. I think it will be approved and then the script will be applicable for 0x also.

Details NOTE: If you are attempting to remove MSE after encountering 0xb01 and attempts to remove MSE are met with an error regarding permissions and contacting your administrator, your PC is infected and it has modified the file and folder structure preventing proper functioning or removal of Microsoft Security Essentials in order to reinstall it.

However, there are times when this won't work. To do this run the FixIt tool from the following links. Click the below link and select Run Now button. After downloading and running for the first time d. Select Detect problems and let me select the files to apply. These particular features are simply not necessary for the majority of us whom know how to navigate Windows and would much rather implement our own security policies and software.

My favorite method for disabling the security-shield overlays is as follows:. Kill the Explorer. This will open the command prompt. No more security shields, just nice clean looking icons for your viewing pleasure. I also have Malwarebytes. I turned it off and it stayed off about a month and came back on by itself.

The program is deeply integrated into Windows, its elimination will result in an impressive series of system failures from Win Update to other key components of Windows. Yeap, manually removed every line from the registry that had name defender in it, and deleted it from Program files and Program data and after restart System went bananas.

I suspected that Defender rather defends against doing some modifications in the Windows, and obviously this is the case. Unfortunately I am not a programmer, but I believe that some good one could cut out this crap from the System. Is there a silent option for this or would it be easy for you to add it? If not, could you publish the source?

Thank you! Just so you know. I downloaded the uninstaller for Windows Defender, but it still shows up in the windows task manager under processes and is still taking up a lot of my physical memory. Many people would agree with you, sadly a lot of that stuff is woven tightly into Windows and will likely be almost impossible to remove safely.

This article urgently needs an update. This sucks incredibly. I finally found a way to turn it off permanently. I found this on my own, you will not find this trick in Google. BUT afterwards I was not able to turn it on again.

So do this trick only if you are sure that you will never use it again. Then restart Windows. The service will not run anymore and you will find NO way to turn it back on!
