Hi guys this proccess in my Task Manager is using a lot of memory and when I stop it my Microsoft Essentials says that I have to restart my computer , can you tell me what is this.I just installet Steam , Video Match and .NET Microsoft Framework 4.0 i don't think that Steam or video match is using that memory...

part of microsoft essencials, what you do about it depends on how much of a problem it is

Why is MsMpEng.exe using so much CPU?

Hi poppey ,

I tried to disable all starting programs and it shows again . I tried to stop it manualy and it shows again.it's not lagging my PC but i'm curious to know why it appears and it start appering today after installing Video Match.

if its a screaming video security essentials is probably scanning it as its running, thats what its there for to scan anything that could be a threat, doesnt mean video watch is a threat but if it doesnt scan it its not going to know that

Well i uninstalled somethings and it doesnt appear anymore , thanks a lot poppey
