Windows 10: My OS drive's space goes up and down by small numbers

As the title says my drive space is dropping or rising by about 0,2 - 0,3 GB every now and then. I've ran Malwarebytes and Defender scans and used CHKDSK but they didn't detect anything. There is also nothing strange in the task manager. Is it a malware or is my drive dying?
