@exxo Hello. I think these are Trojan viruses from the Win32/Wacatac series, which pose a serious threat to cybersecurity, acting simultaneously as spyware and payload carriers for other types of malware. An extremely unpleasant virus, in the fight against which the article https://gridinsoft.com/blogs/trojanwin32-wacatac/ helped me and gave recommendations on how to protect yourself in the future.
