The flagellum is the hair-like projections on the outside of the cell. Prokaryotes are cells that have nucleuses. Eukaryotes do not have nucleuses.
Bacteria are prokaryotes. Viruses are not living organisms, virus is a virus, that is all.
The whip-like projection found in both prokaryotes and eukaryotes that helps propel the cell through liquid is called a flagellum.
It is normal for the euglena to have a flagellum. Of course, any creature can suffer a trauma, or a birth defect or illness, or mutation, which can cause it to lose a part of its normal anatomy. I'm sure that there do exist some euglena which are missing the flagellum, much as there are some people who are missing legs.
A flagellum( plural: flagella) is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells.
If a cell has a flagellum on its surface, it is most likely a type of prokaryotic cell, such as a bacterium, or a eukaryotic cell, like a sperm cell in animals. Flagella are used for locomotion, allowing these cells to move through their environments. In prokaryotes, the flagellum is typically composed of a protein called flagellin, while in eukaryotes, it has a more complex structure made of microtubules.
A Eukaryotic cell does not have a flagellum.

No, Flagellum is singular, flagellais plural. The word flagellum is derived from Latin, meaning whip
The flagellum was a whip used by Egyptians
Prokaryotes have cell boundaries like eukaryotes. It has a cell membrane and a cell wall. There are two types of cell walls: Gram + or Gram-. The exterior of the cell usually has glycocalyx, flagellum, fimbriae, and pili. The glycocalyx can be sticky (a capsule) or loose (a slime layer). The flagellum look like whips and can help move the cell. The fimbriae look like short hairs and allow the cell to attach. The pili are longer than the fimbriae and shorter than the flagella. These allow the transfer of DNA from the cell to another cell.
