Hard Drive is filling up

My hard drive space goes up and down seemingly at random and has been doing so for the past several days. I have kept a record of my disk space for the past hour. It goes from 431,901,884,416 bytes to 431,779,258,368 bytes, then down to 431,743,201,280, then up 431,746,109,440, then down to 431,515,570,176. It is currently at 431,514,259,456 bytes.

Is this normal computer behavior, or do I have some virus or malware that is (slowly) taking up space?
