I won't be renewing either. I've had Avast on my Mac for a few years now and was happy, then auto-renewed again this year and they've sent me the PC version which obviously won't download. I explained the problem, no reply, but now they're sending me pop-ups to pay more for a Mac version! So clearly customer services got my message. In the meantime I think my Mac is completely unprotected... Shoddy stuff. I'm going to have to go with another company to get protected - I refuse to pay twice for the same thing.
