Are you using any kind of "cleaner" such as Iolo System Mechanic, CCleaner, AVG TuneUp, etc? If you are, make sure Microsoft Security Essentials is excluded from the cleaning scan. Sometimes running a cleaner will remove needed files from anti-malware software such as MSE, Malwarebytes, etc. Removing those files can give false reports like: your computer is unprotected; real time monitoring is off; malicious files have been found and so on. I've included a screenshot of CCleaner on my Windows 10 computer as an example of excluding anti-malware programs. (Sorry, my Windows 7 machine is busy right now or I would have used it for the screenshot.

thank you i do that tommorow i see if it works thanks again marsmimar
