Do you think I still need to check anything for malware?
Not required, there is still no malware for the Mac that doesn't also ask for your password. At least not yet. Chances of you having the first known example are probably pretty small.
Still, and especially for your Windows using friends, having an app that can scan and remove Windows malware is handy. As I said, ClamXav and Sophos have free apps for the Mac. The Sophos rated high in a non-scientific test of several different apps, most of which are NOT free. Why pay for something when a free one will do a better job?
Just don't depend on any AV software to be your only protection. You are still the weakest link in any chain to prevent malware or loss of personal data. Think before you click. Install some javascript and Flash blocking extensions for your browser. If you can't get past a button, close the window and try again. If you can't use the site without the same problem, don't use the site and tell them why. If you must use the site, try a different browser.
I'm assuming you are familiar with the "
NEVER CLICK A LINK IN AN EMAIL" counsel that we hammer home almost weekly. You can also disable remote images and html viewing of emails for a little more protection. html and most images are for useless stuff better viewed in a web browser. Email is for information, better known as text!
That's my opinion, but that doesn't mean I'm
wrong!
