1) An OS9 extension won't execute at all if you're not running in OS9, and some extensions won't run even in Classic. 2) Converting completely to OS X will obviate all this. 3) Sevendust looks like a real old virus. This article http://www.defyne.org/agax/additives/sevendust.html hasn't been updated in 6 1/2 years. (The Symantec article is undated.) I don't know if his links still work, or if the code he has will do the job.
