Windows 10: Trojan: Win32 / Casdet! Rfn OVER Zotero on W10

My W10 laptop is infected with the "Trojan: Win32 / Casdet! Rfn" that windows defender (WD) detects when I use the Zotero in the version of the program installed on the laptop, which also syncs with the Zotero in the cloud. I have tried to solve it, definitively, using the WD, the Microsoft Safety Scanner and Malwarebytes Free and uninstalling and reinstalling the Zotero "stand alone" from my laptop, but shortly after starting the Zotero the Trojan appears again, always in a folder with the same name hanging from root paths / Zotero

how do i remove trojan win32 tiggre!rfn and win32 detrahere.B!dr, windows defender does not detect

This is a new computer purchased around Xmas. Computer has been lagging and there are programs in the background running that I don't recognize and they won't let me end task or delete program. Ran windows defender scan, Malwarebytes, adware cleaner,
and even rootkills and found nothing. Ran Farbar Recovery Scan Tool and it said windows defender detected Trojans win32 tiggre!rfn and win32 detrahere.B!dr and did not do anything with them. Also ran scanner from Microsoft website and it found nothing wrong,
what should I do?
