I would've never suspected that a virus was responsible since those disks where never used by me (came with an Amiga500 I bought from a friend 15 years ago). Also the office and write disks have most likely been altered cuz while browsing user created files are present , hence the virus.
Using original software disks to store work files?
The page disk error is a bit odd , it has an error at the start but it boots just fine. Attempts to image this disk in various ways causes some resulting dumps to not boot at all , maybe it's some sort of protection?
Thank you very much for your time and patience
