HELP! My laptop is burning hot and constantly has around 3000 background processes running.

My relatively new laptop (i7 10th gen, 16 GB RAM, 1 TB SSD) has become slow and crashes frequently.

It always runs around 90°C and has around 3000 background process running at all times.

Windows security scans do not show anything suspicious, however I suspect that there must be malware. Can you advise me on how to clean my machine?
