a regular delete operation removes the "link" to the data so it can't be found anymore. metadata is something else.
but yes, once a file has been deleted the normal way the os can't find it anymore hence it can't be used for anything anymore unless the evil virus has a data recovery routine included which would be quite useless in most cases because the old data can only be recovered as long as the space hasn't been overwritten yet.
