So, I know that OSX isn't prone to get viruses, and I know that Windows viruses can't run on OSX, but I have a question. Before I turned to Mac, on my Windows laptop, I used to use... let's say 'iffy' sites to watch TV programmes and films (1channel). Then last year when I got my Mac, I used the same site for a bit, but gave up on it. I've ran numerous scans on my MacBook, and it always comes back saying it's clean, even after I had used the site. On my Windows laptop, when I used the same site, my laptop came back as being clean after running avast!. A friend of mine who runs Windows on her netbook uses the same site I used to use to watch stuff online, and she's just told me the site has infected her computer with loads of viruses... which I didn't understand because my computers always came back clean. So yeah, my MacBook comes back clean, therefore nothing is on it, right? How come it's infected her laptop, and never did anything to my Windows laptop?? As I said, I haven't used said site on my MacBook in over a year, and I run scans on my MacBook fairly often - I still have a Windows mindset with these things, even though I know I don't need an AV.
