Clamav needs a " shared library " package to read the scan but I do not have any idea of what to look for in the massive package database. Can you please inform me which one it is? Thanks.

cousinlucky,

Open a Terminal and issue the following commands:

Check whether it has been installed or not:

and also if it still does not work please post the exact error message (at least).

version
ClamAV 0.102.4/25923/Mon Sep 7 09:37:02 2020


error message
could not display "/usr/bin/clamscan

There is no application installed for shared library files.

how did you produce this message? On gui or command line, what's happened (exactly)?

Maybe try

at the command line, (it should tell you the files needed for it).

I used the command line to run it and went to the file /usr/bin/clamscan
it was there that I got that message when I tried to open the file.
If that is not supposed to be there than I am being prevented from ever seeing a scan of my computer because that is the message I get from all the other scans too.

I can not translate that.

the output of ldd is correct (as far as I see).
I need to know what do you mean by "it was there that I got that message when I tried to open the file."
EXACTLY what did you make and exactly what's happened? (line by line)

after using the terminal for clamav I went into " computer " on my desktop and open the " files " I opened usr and then I opened bin. Then I went to clamscan and requested a display. That is when I was told " there is no application installed for shared library files.

probably would be nice to show a screenshot. I guess you selected (clicked on?) a lib*so (which is s shared library file) instead of the executable.

Ah a screenshot

no, that is not the one we need. we need a screenshot before you click on something.
Also probably would be nice to check the properties of that item.

This just means that your GUI filemanager does not know what to do with an executable when you double-click it.
Even with the command line, you cannot "look" at an executable because it's compiled into machine code.
Well, you can try things like 'cat /usr/bin/clamscan' - this will instantly infect your terminal with a horrible virus!
Or 'strings /usr/bin/clamscan', that the safe version.

/usr/bin
/usr/bin/clambc
/usr/bin/clamscan
/usr/bin/clamsubmit
/usr/bin/sigtool

This appears in the terminal for clamav. This screenshot is of /usr/bin
