Microsoft Security Essential does this happen to anyone else?


Recommended Posts

So I installed the official beta and had to turn off the real time protection. With it on it slowed down my computer completely. Both in XP and Vista. According to my CPU monitor sidebar my two cores were both at 100% from the time my computer would start up till I turned off real time protection.

My specs meet the requirements (both my desktop and laptop run on dual core CPUs clocked at over 2GHz and with 3GB of RAM). So I don't know why it would take up so much processing power. I have never had this happen with real time protection on any other security software.

Has anyone else had this issue?

I haven't noticed any CPU spikes or excessive ram usage. I suggest you submit the feedback through the Connect site.

It runs alright for me on my desktop PC, which is a Pentium 4 2.8 GHz with 1 GB of RAM running Windows Vista SP2, but I have noticed that MsMpEng.exe's CPU cycle usage does occasionally "spike", however just about all anti-virus programs do this (two that I can think of off the top of my head being Avast! and NOD32).

Its fine for me, nothing excessive.

Sorry for the following off-topic question, but is Microsoft Security Essentials meant as a replacement to

things like AVG and Avast? I assume running MSE alongside a currently installed AV is not recommended.

Yes, it is a full free security suite (sans firewall).

2 days of use, real time protection enabled. No noticeable slowdown, CPU spikes or excessive ram usage here.
