ClamAV will match on multiple signature types.  By default it will only alert on the first match, but you can configure this differently.

hello everyone

i can see that there are different types of signatures in clamAV.
there is md5 hashes, rules, byte signatures.. etc

when I do a scan on a file, does clamav extract only one of signature of
the file or does it extract multiple of signatures of the same file and
then compare it with all types of signatures?

thanks!
