Yesterday at night i updated kaspersky security cloud from 2020 version to 2021, and today when i turned on the computer since morning, kaspersky anti-virus keeps using 35 ~ 40% of cpu for a few minutes, which is also causing the CPU to get hotter than usual. After a few minutes, kaspersky stops using the CPU, and some minutes later, the same thing starts to happen again and it stays in this situtation over, and over again, as long as the computer is on. I tried to close almost all the programs, and also restart the computer and none of that solved the problem.

 

Here is a screenshot of the problem ocurring:

 

GSI Scan is attached to the topic. 

@Krister67

> Uninstall KSCloud Trial > reboot

> Install KSCloud Free  > reboot

 

I did that but it still installs the trial version.

@Krister67 Personally i should keep and evaluate the trial version during 30 days.

Another option is to uninstall the trial version with the removal tool for Kaspersky  (KavRemover).

I give up!

I ran the “KavRemover” rebooted as prompted, then ran the free version installer “ks4.021.0.44.1537en_25100.exe”, after installation I login to MyKaspersky account to activate the application and it still is the Trial version….

Now it says the key is blocked.

Back to Defender……. again…..

@Krister67 We tried to help you but your issue is a case which should be raised to K-Lab Tech Support which is unfortunately not available for Kaspersky Free or Trial products.

Well, there is a key (even if it has been blocked by the many activations) but then it is actually not the free version

Same issue here with security cloud free on windows 10 Latest 2004 update and 21.1 security cloud.

 

Kaspersky CPU usage is at 42% constantly with maybe a few seconds where it drops to 0 then gradually ramps back up again, this is all with the laptop at idle and no programs running.  This coincided with the latest windows update so there is obviously a compatibility issue there.
 

Have uninstalled for now until this is fixed.

@Tommy87 Welcome. Are you under OS Windows 10 - May 2020 update (version 2004) ?

Hi Berny

 

Yes, Windows 10 OS feature update version 2004 which only installed yesterday, that’s when the cpu usage issue started With Kaspersky.

@Tommy87 Thank you for your feedback. Please see above instructions from @richbuff  how to submit a request to K-Lab Technical Support

I have the same issue since the 2021 update. Kaspersky spins the CPU on 35-40% almost constantly. I tried doing a clean uninstall, but it didn’t solve the problem. I’m not using any of the Kaspersky browser addons, and the phenomenon doesn’t seem to be tied to if my browser is running or not. (I’m using the free program version, not sure if I should open a new thread instead on that subforum.)

Edit: Removed the attached GSI report for privacy after receiving a response.

The same issue is happening to me and it is EXTREMELY annoying! Please fix this! I even turned off rootkit scanning. I tried everything and this was never an issue until version 21! (Not an issue on version 20)

Its still an issue before and after patch a is installed.

 

(My CPU is an Intel Core i7 8550U clocked at 4ghz w turbo boost BTW. (4 cores, 8 threads)

Program version: ​​​​​​

CPU can turbo up to 4ghz

 

@Michael912873 Welcome. Please contact K-Lab Technical Support.

I have the same problem with the free version of Kaspersky Security Cloud 21.1.15.500.

Everything was fine before the update.

 

I had it as well, I solved it by uninstalling the program, then reinstalling it from the site. It has been working normally, I guess from now I’ll download it from the site now instead of updating through the application.

Try uninstalling it and redownloading using the installer from the site. It worked for me. Performance issues were fixed.

I already tried that and it did not solve the issue

If CPU high usage issue persists - please create a request to Tech Support

Patch B was released (I wish I could find the patch notes because its ALWAYS a pain) (Can staff please link me patch notes) [Also please make it easier for the user to read the patch notes like Avast does]

It seems to have NOT fixed the issue! My CPU usage continues to bump up to 40% and my fans rev up every 20 seconds or so lasting around 10 seconds each!

UPDATE: It seems like it only goes to 40% constantly when I am in chrome then when I minimize it it still stays there but takes a while to settle down

Here is an image of the usage after entering chrome. Notice the CPU usage go high when chrome loads then back down when it finishes. Then Kaspersky kicks in and uses 40% of CPU in the background. 

You can see the usages decreases ALOT when I minimize google chrome (after a moment)

Goes WAY back up when I re-enter google chrome

 

Stable kaspersky load on my system. 50% from kaspersky is unacceptable for me

All from kaspersky. Likes to switch usage of cores for some reason

The google chrome load (On the left and right is the idle load)

Above you can see that kaspersky is using the 4th core.

 

With this image, kaspersky is constantly using the cpu right now and it has switched to the 3rd core.

 

Patch B

 

Turning off the web antivirus did not make a difference!

This is perfectly normal
