Trojan scheduling tasks

Some trojan is scheduling tasks on my PC, where every 7 or 10 days a folder is created in "Temp" with a generic name like "tmp4DC5" containing trojans such as "HEUR:Trojan-Dropper.Win32.Convagent.gen" and "UDS:Trojan.Win32.Agent.xcaoop". Although Kaspersky can delete the malicious file, it cannot find the one responsible for creating it. The same applies to other security programs such as Malwarebytes and Windows Defender.

I used "Revo Uninstaller" to uninstall programs that I considered suspicious, disabled some programs from PC startup, reviewed scheduled tasks (but found nothing), and installed Sysmon right after the last attack.

Now I'm waiting for the trojan's next move so I can check the Sysmon logs. Is there any chance I can remove this Trojan without having to format my PC?

Does anyone have any advice on what I should do?
