AFAIK viruses don’t have anything like flagella or cilia, they can’t really move. Instead they rely on currents etc. to move them around and hit cells they can attack.
Unless I am mistaken, viruses don’t move on their own, they require something to push them where they are going.
Whoops didn’t mean to mirror what hhyyrylainen said, I started my post then had to stop.
The good thing about this for viruses is that they don’t use energy to move.
