Okay, here's the deal. Our office has Roadrunner with connections for up to eight computers. We currently have four computers on. One of the computers just got a virus. The office manager is convinced that the virus came in from one of the other computers because they have all kinds of "protection" on that particular computer. I run a weekly virus scan and spyware check and very rarely have any problems at all. I never use the Roadrunner email system. I have the line plugged into my computer and use Internet Explorer or AOL. Is there any way that my computer could have infected another computer on the Roadrunner system? If not, how can I explain this to my office mananger?
