Hello all, I am trying to download Microsoft Security Essentials, and it is giving me this nasty error repeatedly. Can it be possible that this error is because of anti-malware software already running on my computer? How do I solve it now?

Hello friend, I have previously solved such errors, and I am assuming that Total Anti Malware Protection can be installed on your PC. This software disables MSE from functioning and will want to launch itself every time in place of MSE. Here is a full-proof solution:

  • Open the Run window by pressing Windows logo key and R key together. In the Open field, type regedit. Doing so will open the Registry Editor.
  • Now, go to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\Current Version\Image File Execution Options.
  • Look at all the items, and if an item contains Debugger as a value, then that particular item is being redirected.
  • You must remove (delete) the entire key of the above item.

This solution has previously worked for many people and it will help you too. Thank you and regards.
