    I seemed to have had a keylogger or virus on my MAC. I had to reformat it.

    I used google, i am relatively new to MACs, and the method I used was inserting the disk 1 while holding down the option key. It is reformating as I type this.

    My question, does it completely erase everything? I know with PCs, a simple reformat like this does not always remove all the problems.

    If you selected Clean Install during the installation setup, it will remove everything.
