And a word of advice for your new Mac:
When you run into a problem, please try to lose the habit of instantaneously blaming it on a virus.
I know that working with Windows PCs fosters that kind of excuse for problems, but for Macs (which have not been affected by a virus in quite a few years), it's just not feasible.
Bugs? Yes, all programs have certain quirks or problems.
Virii? On a Windows PC yes; on a Mac, no.
It's really that simple!
