CPU usage high until i open task manager

[HawkAngel]

Hello,

I recently noticed that when I am running my PC and open task manager I see the CPU usable at 70-100% for a moment before it drops to about 10%. I've followed the advice on https://forums.malwarebytes.com/topic/241749-cpu-usage-high-until-i-open-task-manager/ (as best as I can) which hasn't been able to fix it. I've ran multiple scans of Malwarebytes and while its detected 1 or 2 things it hasn't made a difference.

 

Thanks, Hawk

Not sure if it changes anything, but when I've ran Malwarebytes I've had task manager open to keep CPU from being at 70-100.

Hi,  @HawkAngel

    

My name is Maurice. I will be helping and guiding you, going forward on this case.

The CPU usage can fluctuate depending on all sorts of conditions.  It  ( high cpu usage  at some moment in time) does not mean that there is some kind of "infection".

For example, it can be due to the mix of tasks ( jobs )  and programs in use.

Do NOT use other cases to compare with.  Cases can and do differ.

The important thing here is that Malwarebytes for Windows shows "no malware" on board.

 

I would suggest a free scan with the ESET Online Scanner
Go to https://www.eset.com/us/home/online-scanner/

Look on the right side of the page.  Click Scan Now
It will start a download of "esetonlinescanner_enu.exe"
Save the file to your system, such as the Downloads folder, or else to the Desktop.

Go to the saved file, and double click it to get it started.
When presented with the initial ESET options, click on "Computer Scan".

Next, when prompted by Windows, allow it to start by clicking Yes

When prompted for scan type, Click on Full scan
Click on the radio selection "Enable ESET to detect and quarantine potentially unwanted applications"   and click on Start scan button.

Have patience.  The entire process may take an hour or more. There is an initial update download.
There is a progress window display.
You should ignore all prompts to get the ESET antivirus software program.   ( e.g.  their standard program).   You do not need to buy or get or install anything else.

When the scan is completed, if something was found, it will show a screen with the number of detected items.  If so, click the button marked “View detected results”.

Click The blue “Save scan log” to save the log.

If something was removed and you know it is a false finding, you may click on the blue ”Restore cleaned files”  ( in blue, at bottom).

Press Continue when all done.  You should click to off the offer for “periodic scanning”.

This scan also found nothing to remove, but no matter when or what else Im running, this always happens when I open Task manager, CPU goes from insanely high to super low.

The displays in Task Manager can well be momentary happenstance.  If you suspect some infection, you have to run security check tools.

Outside of that, you would need to review all the auto-started applications on this Windows.

Thanks for the report.  This pc has BitDefender.  Q:  Did you do a scan with BitDefender ?

[ 2 ]

Close the opened programs that you do not need to be running at this time.   Then do a special scan with Malwarebytes for Windows.

Run a scan with Malwarebytes.
Start Malwarebytes from the Start menu.

Click Settings. Then click the Protection tab.
Scroll down and lets be sure the line in SCAN OPTIONs for "Scan for rootkits" is ON
Click it to get it ON

Click the SCAN button.
Select a Threat Scan ( which should be the default).

When the scan phase is done, be real sure you Review and have all detected lines items check-marked on each line on the left. That too is very critical.

Then click on Quarantine selected.

 

Be sure all items were removed.


When that is completed, kindly send the report.
In Malwarebytes.
Click the Reports button ( on the left )
Look for the "Scan Report" that has the most recent Date and time.

When located, click the check box for it and click on View Report.
Then click the Export button at the bottom left.
Then select Text File (*.txt)

Put in a name for that file and remember where the file is created.

Then attach that file with your reply. Thank you.
