A computer threat database probably provides information related to
that particular virus.

FWIW mounting a device on a Linux machine requires root privileges. To
allow a user without root privileges to mount any device by a mouse
click is not necessarily a good idea and definitively not a Linux
default. After installing a major distro with a bloated desktop
environment access to all devices, without root privileges, much likely
is allowed, but it's still not a Linux default.

Just do a test and try to mount and unmount a partition by command line
using the related util-linux commands. (The Ubuntu package name is
"mount", but actually it's just because Ubuntu splits "util-linux" into
several packages, something that IMO makes no sense. The util-linux
package is "essential")

$ mkdir test
$ mount -wL moonstudio test/
mount: /home/rocketmouse/test: must be superuser to use mount.
$ sudo mount -wL moonstudio test/
$ ls test/
bin  boot  dev  etc  home  lib  lib64  media  mnt  opt  proc  root  run  sbin  snap  srv  sys  tmp  usr  var
$ umount $(blkid -L moonstudio)
umount: /home/rocketmouse/test: must be superuser to unmount.
$ sudo umount $(blkid -L moonstudio)
$ rmdir test/
