What are the different shapes of a virus?

Virus come in two shapes:

The helix (plural: helices) is a spiral shape that curves cylindrically around an axis. It is also a common biological structure: many proteins have sections that have a helical shape, and DNA is a double-helix of nucleotides.

Viruses are obligate intracellular parasites, meaning that they are completely dependent upon the internal environment of the cell to create new infectious virus particles, or virions.
