How do I remove intruder access from my laptop?

Question

Malware

Shortly before turning off the laptop, I saw that someone (an attacker) was trying to enter my PRIZM account. I have a laptop on a modem. I pulled out the modem. -something was mining on my laptop. Tell me what to do, how to get rid of an uninvited "guest"

Answer 1

In general, in such cases, do the following: copy important data to removable media, a flash drive, for example. Completely delete all data from the hard drive, install a new operating system, then the maximum licensed antivirus from Kaspersky Lab, then install other software for work and life.
Why? Yes, because no one will help you understand how and where the attacker gained a foothold.
And only then transfer everything from the flash drive back.
