I've gotta clean up a laptop, running OSX (not sure which version, can get it later if it's required). Just the usual malware running about, doing browser redirects, browser popups etc. Happens in both Safari and Chrome. As far as I'm aware no other issues with the laptop. Can anyone recommend some cleanup software? Free would be ideal, I'm hoping it won't be a frequent request. No antivirus on the machine right now, not looking to install one if I can avoid it. On Windows I'd usually go straight for Malwarebytes or something, but I've never messed with OSX much to be honest. Any tips appreciated.
