I connected an NTFS drive to my Mac and ran avast free scan. A Trojan was detected but it couldn’t clean the virus due to the NTFS file system. I disconnected the drive and my Mac shut down abruptly. when I booted back into to Big Sur I left the drive unplugged and loaded my ubuntu VM so I could remove the trojan from the NTFS usb.
I have run Bitdefender and avast scans on my Mac system and both came back clean. Any possibility my Mac could be infected?
