preventative maintenance?

I switched from Windows in June, and I must say that Mac is definately just... better I guess.

but I have had somthing that's been bugging me the entire time I've had my iBook.

and that is that I haven't been doing the regular weekly maintenance that I had to do on my PC. Defragging, anti-virus scanning, Ad-ware scanning and the like.

why is it that I'm not doing this on my mac?
Should I be? and if so, what programs should I use?

thanks in advance.

No spyware to scan for
No viruses to scan for
OS X automatically takes care of the file system

Once a month or whenever you install a program or update go to Applications -> Utilities -> Disk Utility

Click the Macintosh HD and Repair Disk Permissions in the first aid tab

Thats really all that you need to do

Well that seems deceivingly easy...


...that's what I love about my mac... it's rediculously easy, and is low demand compared to my PC.
