Scroll down to "Decide whether to erase your startup disk" for instructions on how to erase and install OS X.

Buddyme2's answer should get you there for reformatting via recovery.

My additional tip would be in reference to your request for a Mac dban alternative, for that the 'dd' command is great. I'd suggest looking into it!

 

Also note that reformatting is good against malware but if you believe your firmware has been compromised a reformat won't do. Luckily the chance of that sort of infection, especially on Mac, is extremely slim.

are you sure you have malware? it's pretty rare on the mac. did you install and run malwarebytes first?

Thank you guys for the replies. Malewarebytes returns that the mac is clean. I think the mac is clean... This can be a bug introduced by some update.
