Chosen Solution
Hi. I think my laptop has a virus in it, which can not be identified by windows security. In “Windows security” - ”Virus and threat protection” - ”Exclusions”, the exclusions are adding to list without my permission. If laptop is not in use for 4 minutes, the CPU stars running at 100% and as soon as i touch mouse or type any button it gets back to normal work, also if the Task Manager is opened this “thing” will not occur (all works normally). I was advise to (buy) install Kaspersky antivirus. Do you have another option to deal with this kind of abnormality? Thanks!))
A permanent Antivirus solution like Kaspersky may be best to prevent future issues. But for the current abnormality, a free download of Malwarebytes (https://www.malwarebytes.com) can work. Having a data backup to OneDrive is always a good idea, as well.
Could try malwarebytes, or use a trial of an antivirus. As asked, if you have a backup, would recommend a re-image of the system.
