How do I get rid of malware?
I have a MacBook Pro running Yosemite.
I thought I was downloading a new version of Java and now seem to be infected with some sort of malware. Pop ups all over the place.
I was always told not to worry about virus protection with a Mac, but maybe that's no longer true. How can I get rid of what is causing these problems?
