Thank you!

I've had to switch over to mac every since my PC fried up (passed down by my aunty). My aunty is not an exactly tech savvy person so she doesn't know how to protect her mac from viruses or even what a virus is, and when she handed the mac down to me, it was full of files and I need to clear up space because I think she maybe has downloaded somethings secretly running in the background taking up space. Is there a Malwarebytes for my version, if not what are some free options that can be used on my version?
