I love how people say buy a MAC....

If I bought a MAC I still would put windows on it either in a Parallel or Boot Camp. 99% of my application only run on the windows platform. The 1% is my wife SIMS 3 which can run on Windows/MAC.

I love MACs but I have no need for them, other than iTunes and surfing the web, for me that would be a waist of money.

Run Malwarebytes, SuperAntispyware. Run these in safe mode (tap F8 repeatedly when you reboot your computer and select the first safe mode).

Again I love Macs but for me it would be a big expensive storage/net only computer. I would not be able to run my application on it.
