Do you know what processes occur if/when one uses 'First Aid' (Disk

Can it REALLY fix things which are wrong?

Of course but then again it does depend what is wrong.

I was thinking about being attacked by malware.

think about other things, namely not opening links or attachments in
emails or running software from unknown sources. if you do that, then
you don't need to worry about malware.

I'm not sure that's true anymore was reeading about handbrake and how for a
day or two the auto update installed malware on a Mac, not sure it caused
problems as I have't looked more deeply into it, that sort of thing is a
sunday job for when I have my cruicifx around my neck ;-)

handbrake is not codesigned. apps that aren't codesigned can be hacked.
the bad guys took advantage of that.

plus, the bad guys hacked the creators of handbrake, not the end user.
