Windows 10 Task Manager shows higher cpu usage when opened

[PaulU]

So whenever i open the task manager it shows 40% CPU usage for a split second. After that it jumps right down to the usual 1-4% in idle.

I googled around and many people think it's a bitcoin miner or something. But if that was the case my PC fans would ramp up. Which they don't.

I don't see what progress is using the CPU because in that split second every process shows 0% CPU usage.

When I check resource monitor it shows the usual 1-4% CPU usage. But with the resource monitor open, when i open task manager it does the same thing, while in RM it goes to about 10% for a second.

Is it just Task Manager launching that is causing this? Or should I get every Anti Virus scan in existence to see if it's a miner?

I use Bitdefender btw. heard it's good.

Thats properly taksmanger itself being started. Wich CPU are you on? That helps to guess how much load launching TM should produce.

 

About the miner and virus stuff: If it was a miner it would be a constant load and also CPU miners are out of fashion because the are suuuuper slow. Antivirus: yes antivirus takes a bit of your CPU power, but not that much and not so much when launching TM. Thats not how antivirus software works.

Um, yeah, that's becuase when you start task manager or any other program CPU usage spikes up because the CPU is being used to open the program....

yeh that will be TM loading. Short boost on one core I guess. So absolutely noting to worry about . And nice CPU choice!

thanks guys! I'm just always worried about viruses nowadays.

Happens to every pc I've owned and is normal.

Burst Usages when Opening a Task..

 

Also...to think about..

More specifically...declockingCPUs on idle and then using PC will see higher CPU usage bursts than leaving the CPU at 4Ghz and using less to do the same job.

PC declock at idle, so 800-2000Mhz idles. Will show more BURST Usages..

Then it needs to ramp up clocks when you open something.

The normal PC guy and Windows install is no longer the main target of hackers. also not private guys. Thats because peeps got more aware, Windows got more secure and frankly there is not that much to get on a private persons PC. MUUUUUUCH more interesting are IoT devices, printers, (some) routers. Craptastic  security in the first place, people dont update em, peps dont change standard passwords etc etc. That is much more lucrative than stealing your personal d.... pics form your rig . Also online scamming etc is more lucrative to get money from private persons.

 

Therefore: Keep your shit up to date (pc AND every device connected to the iWeb), dont go on sketchy sites and think before you click. With that mindset I never had a virus and am only using windows build in defender. 

 

EDIT: Funny thing: AV software BEING the security risk (tracking everything you do on the web): https://www.vice.com/en_us/article/qjdkq7/avast-antivirus-sells-user-browsing-data-investigation

I used to use Windows Defender too. I got paranoid after seeing login attempts on my microsoft account (which is perfectly normal). so i got Bitdefender. It found like 8 miners in my recycling bin. and one trojan. Defender never saw those.

A lot of stuff anything detects are false positives and of varying importance.  It detects utorrent as "recommended for removal", so is my actual miner software that I use, and various other small bits and pieces I play around with all the time, none of which are viruses.  The scan result shouldn't be the end all and be all of virus scanning, when you look through them a vast majority of them are actually proper files.

Yeha exactly. I had Sophos (enterprise, from work) and it freaked out about everything I did with bitcoins. Heck it even detected my F@H install as a virus

For task manager, I just wanted to add, that like FPS count in games, it cost performance when you have it open.

It needs CPU power to do get (and display) the information on processes. That is why you also have speed control under the "View" menu.

So when Task Manager is open the CPU will never really show it is 0%. You can hide the problem by having more cores on your CPU, and faster one, but that is about it. For example, if you have 100 cores, because the CPU usage is in percentage, if you have the Task Manager or a single tread process consuming 100% of one of the cores, because you have 100 of them, it shows 1% usage, as only 1 is being used at max, and the rest is at 0%.
