There's no such thing as malware for Mac and there never has been.
MS Office on Mac has been there for a long long time..... http://en.wikipedia.org/wiki/M...
The installation might be a bit tricky ( since Google removed CynaogenMod installer from the Play Store ) . I downloaded the installer from the CM Site , ran the app, followed the instructions and then it installed CM 10.2 ( Android 4.3 ) on my GS3.
I hope with additional funding, CM can come pre-loaded on more devices - a lot of Android devices are being held back by their software. ( cartoonish TouchWiz and LG's even-more-cartoony skins are at the forefront here ). Not only is it aesthetically pleasing, it is more secure, gives more choices to the user and generally makes your phone a better phone.
I hope CM gets more funding and does a stellar job - there is not reason it shouldn't - CM team have already been doing a stellar job
