Windows 10: MsMpEng.exe Windows defender services

Dear Experts,


This windows defender is consuming lot of memory resources. its practically near impossible to work with large files in my laptop windows 10.

I checked, and no scan is in progress.

Still the consumption from this services is continuously high and not going down. I dont want to terminate this process or disable the defender also.


can someone share some experience in this regards.


Thanks in advance for your time and support.


Regards,

Programs Slow To Open Due To Windows Defender (MsMpEng)


This is something that I've noticed since Windows 8, but Windows Defender make some programs so slow to open. It's pretty noticeable on the programs that it does it on as it takes approx. 20-30 seconds to open them, even from an SSD, and if you look at Resource Monitor listed by CPU usage, you can see it's due to MsMpEng.exe running a scan before the program will open.

It would be understandable if it was doing it the first time the program had ever ran, or if the program wasn't signed, but that's not always the case. Canon DPP for example isn't signed, so presumably that's why Defender keeps scanning that, however here's an example of another program (SyncBackFree) that is signed, but yet Windows Defender still wants to keep scanning it on a daily basis despite nothing changing since previous scans.





Obviously I can add individual programs to the Windows Defender Exclusion list and exclude them from real-time protection, but what it is that Defender doesn't like with certain programs that is feels the need to keep scanning them daily? Is this a Microsoft problem, or is it down to the software not adhering to some sort of best practice policies Microsoft have laid out? There must me something that makes Defender treat it as potentially signed malware?

 

Securing Windows 2000/XP/Server 2003 services HOW TO

I will try changing their settings sometime, the one thing I've noticed about this guide is that it doesn't list the Windows services that NEED to be left as local system, so some people might not be too sure what they're doing and worry about any that aren't listed. Just a suggestion that you might want to include in any future revisions. *Smile

The non-default ones I have that you have not listed are:

.Net Runtime Optimization Service v2.0.50727_X86
Ati HotKey Poller
ATI Smart
AVG E-mail Scanner
AVG7 Alert Manager Server
AVG7 Update Service
BlueSoleil Hid Service
Bluetooth Support Service
ewido anti-spyware 4.0 guard
iPod Service
Messenger Sharing USN Journal Reader Service
Service Layer
Windows Defender Service

The problem is that the only ones of these I actually use are The AVG and Windows Defender services and occasionally the "Service Layer" service (related to Nokia PC Suite) and the "Messenger Sharing USN Journal Reader Service" (related to WindowsLive Messenger). Anyway, I'll see how much I can secure those and post back how I get on. I'll try to test it sometime this week just I'm a bit waring of changing the AVG settings because the only way to test if it was still working would be for a virus to be detected... and I' rather I didn't get viruses!
