CPU Spikes in a Hyper-V VM

And yes...horrid performance problems, especially when it was at 99%. Taking forever for end users to access files on the shared drives.
-
Is that a Sybase DB running? That is a lot of CPU there.
-
How many vCPU do you have assigned?
-
Are you doing full scans or targeted scans? Do you have any files/folders in the exclusion list?

That is the DB for Symantec SEP...again, currently not running...
It just happened again now:
We are running 2 virtual processors.

Currently, Anti-Virus services are off. Going to check the settings again tonight when I turn it back on after hours...

Should I give it 4 CPU's? Is that not excessive for just a file server, albeit heavily used one?
-
You should be giving less vCPUs, not more.

Not likely. But it depends on many factors.

So perhaps try one tonight?
Very un

very unlikely to be the culprit but doesn't hurt to try.

Weird posting thing there.

Got to try something...because I am taking 1/2 day off tomorrow...LOL. Will try tonight...

Important to consider that malware is a possibility. Do a scan with some third party scanners to improve confidence. Such a new system, unlikely to be infected but you never know.

If you bring up performance monitor, what files are being written/read? Even if the disk activity is relatively low, it gives you an idea of what the process is doing by the files it's interacting with.

It had no malware.
So, powered it off and took away a virtual CPU.
It took forever and a day to boot up and even when I finally got a login screen, it takes forever to get its services started (Welcome, Policy Registration, Local Session Manager takes forever to come up). Then a black screen for a good while and finally the desktop. And waiting and waitng for it to let me input. Server Manager creeps to a start. The right click I did on the task bar so I could get the task manager took over a minute to give me the context menu...finally got task manger up and for sure, back to 99% CPU with Symantec and Service Host taking most of it.
This is terrible It has to be some kind of VM setting wrong. But it wasn't this bad yesterday.
I am about to bring up resource monitor but it is taking forever as well...

Expand the middle row and sort by total.

THis is at night with no one using it?
