Hi, Guys. Been reading some of the responses to the virus question. I had BIG-TIME problems with my Mac sometime back. Someone suggested that I use TechTool Pro 3. An amazing program! It does everything. I even had another Mac B&W G3 sitting here that my son was ready to scrap because of proms with it. I instaald TechTool Pro 3 on it and it works fine now. FYI, Ed
