Often times when surfing the net on my desktop PC, Norton Anti Virus will go crazy with programs/adaware/hacks/exploits trying to install itself on the PC. Do I need to worry about these getting installed on my PPC?

I guess you should always be cautious, however, there are very few viruses/Spyware written for the WM2003 platform. I do have Symantec AntiVirus on mine. I had it running for about 8 os. now and I've never had a virus.

I read a lot of threads in axim site were they say this is really not a problem for PDA's... (until so far!)

Is PPC software totally different to normal Windows software?

Hopefully they'll try and exploit a mac before a PPC then

I think people who write destructive code want to inflict maximum damage and the PPC market is just "a waste of time", but I also run Norton on my 4700 anticipating the day someone gets bored and sends some crap my way.
