MSE thrashing disks after boot.

This is really the only thing that's preventing me from installing MSE.

Is it really that annoying?

Annoying? No I say it is not. While it may scan, it can be disregarded because it will not interfere with you using the computer. It runs in a low priority background process. It is using all the free and idle time to get work done. So use your computer and forget about it.

All this nonsense about disk trashing in just ridiculous if you ask me. It is like people what there HDD to be used but don't want it to be used...

Also MSE does not scan after boot. However, it will try and scan if the scheduled scan was missed. And it will only do this if the computer is idle for one minute.

This sounds pretty accurate, I have been running MSE since the first leaked beta and have never seen anything like this supposed "disk thrashing" nor have a noticed any performance hit whatsoever... in fact I've never even noticed that it was installed at all after installing it, that's the way AV should be...

Found something that looks like we could stop it checking so much.

1. In Task Scheduler, go to Task Scheduler Library - Microsoft - Microsoft Antimalware
2. Select MPIdleTask, right click and choose properties
3. Go to the Conditions tab
4. Change the drop-down for start the task only if the computer is idle for... to whatever you wish (Ive changed mine to 1 hour so hopefully that'l mean itl end up checking the computer at night)

Of course you could disable this service but I suggest you leave it running but increase the interval. Certainly never actually delete the task entry.

Thanks for all the help you guys.

I'm now leaning towards MSE, once again, after my Kaspersky license expires on a few days.

Why change it in the first place? Just leave it alone!
I do not have that task as it were anyways.

My experience is that MSE restores the MpIdleTask if it is modified or deleted.

This is how I managed to get rid of MpIdleTask:

I created a scheduled task that deletes the MpIdleTasks with the following triggers:
-On an event: When MSE creates the MpIdleTask (see filter below)
-At startup
-At login

The event filter XML:

<QueryList>
<Query Id="0" Path="Microsoft-Windows-TaskScheduler/Operational">
<Select Path="Microsoft-Windows-TaskScheduler/Operational">*[System[(Level=4) and (EventID=106)]] and *[EventData[Data[1]='\Microsoft\Microsoft Antimalware\MpIdleTask']]</Select>
</Query>
</QueryList>

The executed command (Action):
schtasks /delete /tn "Microsoft\Microsoft Antimalware\MpIdleTask" /f

The user should be SYSTEM, and disable everything in the conditions tab.

Bye-bye MpIdleTask !!! :)

Haa...wow back from the dead!


I already posted some information about this before but to help I'll do it again.

MpIdleTask can be found if MSE has choosen to apply it in Scheduled Tasks in the control panel . You need to go to "advanced" tab and click to select "hidden tasks" if MSE has choosen to apply this service you DO NOT NEED TO DISABLE OR CHANGE ANYTHING AT ALL IN SCHEDULED TASKS...TO ELIMINATE THIS action by MSE, all you need to do is go to the MSE main page and select on "scan options" {full scan}. Then allow it to complete the full scan without interruption .
This will signal MSE that is no longer needs to do the full scan via the MpIdleTask which is what results in the constantly active HDD when you leave the PC idle for a few seconds....and may continue this way until ths method has completed the full scan which could be a day or three depending on how you use your PC which can be (and is to me) annoying.

Essentially you are doing manually the same thing MSE was attempting to do automatically.

It appears that this MpIdleTask will be activated by MSE usually following a client update version (eg v2). MSE is trying to be sure that your system is totally clean before it installs the new client version in your system.

Hi,

Thanks for the info, i will try running a full scan and manually and see if MpIdleTask
disappears or not.

But at this moment, I cannot see any notification or warning like "hey dude, do a full scan, or I will do it when you are idle" everything is all green an OK.

@Karmoss:

You won't see any loud warnings like this from MSE, the idea being that it works quietly in the background supposedly so that you are not bothered by it. However it is hard not to notice the constant flickering and noise of a HDD....the auto MpIdleTask scan is a FULL scan that is spread out and only is actively scanning when you leave the computer idle. When you are actively using the PC the scan stops until the next time it is left idle.

When you do the manual full scan you are overriding the automatic full scan and it will be done quicker since the manual scan will be continuous until completion. Usually the manual scan (depending what is on your PC ) can be completed in 1 to 4 hours. While that "auto" full scan could take days, literally. Again like I said before usually this auto scan application only occurs if a major update has been applied to the MSE engine. Like when you update MSE to client version 2.

lol I found this thread googling mpidle ressurection.

MSE is a nuts a/v now what the hell is it doing grinding my hdd everytime my laptop has been idle for 5 minutes, I left it alone for 40 minutes to see if it would settle down, it stopped after 30 and then started 5 minutes later, crazy. Also when I disabled mpidle it reenabled itself. A good a/v shouldnt need to forcefully keep redoing full scans. Also no good app should forcefully grind the hdd when machine is idle, a big no no for me.

I will try your trick if it works then many thanks, if no its bye bye MSE for me. When MSE v1 first came out I dont remember it behaving like this.

Yes, I don't like the way MSE thrashes the disks, either.

Another reason why I use Avast- they do a free Home version.

Low resource usage, fast scans, constant updates.
