Before you think about deleting them, see if you can retrieve clean versions.
I'm not sure if any of these methods would work but it's kinda worth a shot I guess.
A system restore to a point before you got the virus might work.
Or maybe you could try running a full scan of Malwarebytes (antimalware software)
there is a free version. (Or software if you have one.)
Now, I don't think it can disinfect files (I don't even know if that's really possible or easy)
but it might get rid of the viruses on your computer.
Just make sure to do another full scan to make sure the viruses are gone because sometimes
it does take a few scans to completely get rid of them.
I don't know how else I can help. Sorry. Good luck!
