Currently there is nothing that does harm to OS X. There are still a few of the old OS 9 (and below) virus's around but they are very few and far between. Your current AV will easily catch them. Trojans and Key-Loggers are also not a problem with OS X, ditto for <=9.0
The pop-up ads that you see are a result of the web page you are on and are not an indication of Spyware/Adware/Malware. I do not know of any program that is designed to find those sorts of things, on the Mac, as they are written for the Windoze world and as such do not run on the Mac. Keep the Firewall up, the Virus Defs up to date and you should be fine. It is possible to write these sort of things for Unix but it would have to have your permission to get installed.
What Programs/Files do you run that do not have OS X versions? Would I be right in assuming that the "accommodations" you have to make are a result of trying to run your favorite software in the "Classic" mode? If I am, try booting the iBook into OS 9 to begin with. Should solve all your "accommodation" problems.
What do you do for "Cleanups"? Please don't tell me Norton SystemWorks. Do you boot iBook in OS X or do you boot in OS 9? Define slow. Is it slow when running programs or slow to boot? If it boots correctly and then slows down when you run particular programs. Under OS 9 you can allocate more memory to individual programs which will allow them to not use the hard drive as a temporary storage area. Access to and from RAM is much faster than access to and from the Hard Drive. Your iBook has 257Mb of space reserved on the HD for Virtual Memory. A program that needs more memory than is currently allocated to it, will use that 257Mb as Virtual RAM and, as a result of the slow transfer speed, will slow the program down. If you are running Classic under OS X, then the hit will be more as OS X needs a minimum of 128MB to run and only leaves 128MB to play with on the Classic side.
If the machine boots into 9: Once booted, find the program you want to allocate more memory to. You need the actual application and NOT the alias. Click it once to highlight it. Hold down the Apple Key(next to the space bar) and press the "I" key. Select Memory from the dropdown box, it says General to begin with, and you will see the Memory allocation page. The bottom box is the one you are interested in. Add 10 MB to the Preferred Size box and then close the window. Next time you launch that program it will have an extra 10MB of RAM to play with. Try that and see if there is an improvement in the overall speed. you can allocate as much memory as you have left (don't forget that the OS needs memory to run so you do NOT have 256MB spare to allocated around) The extra memory allocation is not cumlulative, you can allocate and extra 50MB to 12 different programs and, as long as you do not try to run them all at once, you will not run out of memory. You can also allocate extra memory to your OS 9 programs even if the machine boots into OS X. However, you cannot do it with OS X programs/applications as the OS allocates memory dynamicaly.
Let me know the answers to the questions and I'll see if there is anything else I can help you with.
Sorry this is a little long, but if you need more Nitty Gritty, let me know
Don't forget the answers
I have a firewall and run a virus checker once a week. Are we subject to the same "key-capture" trojans? Are the popup ads I get strictly linked to the web page I am on or is there some bot buried in the computer?
My computer is running slower even when not on the net. I do run cleanups once a month, but no improvement. Memory is 256 mb with Virtual Memory at 257 mb, Backside L2 cache 256 k, 8 mb video, 5 gb free. A 2001 iBook running 9.2. Some of my favorite software and files would not work under the 10. Already have to make accommodations under the 9.2.
When I last asked this question, I was told not to worry; but with the computer hacker advances, I thought I needed to ask again. Are we still immune or is there more software the Mac world needs to add? Adware and Spybot and Houseclean and whatever else are still listed on the PC side of the house. The terrible "I assume thought" that since there is no major ad compaigns and news flashes, all is right with our world?
Thanks for your thoughts
