It’s completely infected. Likely downloaded through crypto mining software or similar. It attempts to conceal itself by shutting down when Task Manager is active. You’ll need to erase it and reinstall everything. I removed it using some program, though I don’t recall the exact name.
What system was used? Were there any hardware modifications near the time the issue began? I experienced a comparable situation when switching an older laptop (over 10 years) to an SSD. It seemed the SATA controller struggled to process the new drive, generating endless interrupts to the CPU. Interrupts are a method for hardware to communicate with the CPU. Previously, devices like keyboards and mice sent interrupts to inform the CPU of actions such as key presses or mouse movements. Typically, this doesn’t lead to excessive CPU usage. However, if it does, it suggests an incompatibility or faulty hardware.
Have you experienced issues when the computer isn’t linked to the internet? I once faced a miner virus around five years ago that activated only when connected online. I managed to back up everything and erase the drive before performing a complete Windows reinstall. Before backing up, I ran several antivirus tools to tackle the infection (like Malwarebytes AdwCleaner, Anti-Rootkit, Anti-Malware, Kaspersky TDSSKiller) and others I don’t recall using anymore.
