Anthony:
Welcome to Apple Discussions.
To reiterate what have always been told, it is very unlikely that it is a virus. There are no known viruses for Mac OS X in the wild.
Next, I don't think the software you downloaded is responsible for what you are experiencing.
First, try this:
• Shut down the computer.
• Locate the following keys: Command, Option, P, and R. You will need to hold these keys down simultaneously later.
• Turn on the computer.
• Press and hold the Command + Option + P + R keys immediately after the startup chime.
• Hold keys down until you hear the startup chime for the third time.
• Release the keys and immediately hold down Shift key to
start up in Safe Mode.
• Log in and empty Trash.
• Restart normally and log in.
If that does not help try
Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but
Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
A few questions:
You have an iBook G4. What is the processor speed?
How much RAM do you have installed?
What is the total capacity of your internal HDD?
How much available capacity/free space do you have?
Is your internal HDD the one that shipped originally with the computer?
Do you have an up-to-date backup?
Do you have the original install disks?
