Deleting one file in a time machine backup
A Mal/DrodZp-A virus was flagged on one of the Time Machine Backups on an External HD.
I realise this virus is related to Windows OS, but I would like to delete it anyway - also every time I use Time Machine the Mal/DrodZp-A file is detected by the virus software. Unfortunately, the individual file can't be deleted as there was a warning "The operation can't be completed because backup items can't be modified". I would be interested in how to delete this virus file PIC036049416-JPG.zip.69931694-d5c5-4ea9-be0f-o989-3c76e4ef which has been identified as Mal/DrodZp-A.
The route is: HD/Backup.backup.db/steven’s Macbook Pro/2019-04-05-000501/Macintosh HD/cleverfiles/hlink.ref/PIC036049416-JPG.zip.69931694-d5c5-4ea9-be0f-o989-3c76e4ef
The advice I have received is that I must delete the entire 2019-04-05 backup. Is there an alternative way to delete only the specific file rather than the entire 2019-04-05 backup.
Would welcome any ideas. Thank you.
