What security is best for my MacBookPro and iMac?
Apple's Software Update is all you need. Mountain Lion and recent versions of Adobe Flash can update themselves automatically.
I have had some company asking me to join them to 'clean' and get rid of some unused files. Is this ok, the cost if around $40. I don't mind paying but I am a bit worried they might not be approved by Apple.
Don't pay. Run far away. This "clean up" software is junk and will just corrupt your system.

Does this company know you use Mac OS X? If so this is a worrysome trend.
For a couple of years now there have been several scam artists that call you, claiming to be from 'tech support', or your ISP or even Microsoft, reporting that your machine has been idenfitied as being infected and that you need to give them access to your machine to 'clean it up'. In the process of this 'clean up' they thoroughly hose the system by trashing important files and then demand more money in 'recovery fees' to restore the system.
I've laughed in their face whenever they've called me since they have no clue of how to compromise a Mac system, but if they've started to target Mac users then more vigilence is required.
Just Google 'microsoft support scam' for more reports/variations.
