Ok, to start out with I've been a Mac user since 1993 and I know there are (as of yet) no Mac viruses. I'm just hoping someone here can help me figure out what my IT dept is telling me so I can solve this problem. I've been bringing in my Macbook Pro to work and using that as my main computer since I started this job. The company gives us crappy under-powered Dell PC's so I would just rather use my own machine, and no one seems to care. So last week I'm working away and suddenly I have no more internet access. I tried swapping Ethernet cables with no luck, so I go in and talk to IT about the problem. They tell me that my IP address has been blocked because I've been sending out spam emails. They know, of course, that it wasn't really me who did it, so they figure I must have a virus or a trojan on my machine that is doing it. Of course it can't be a virus, but I'm pretty sure I remember hearing about some trojans that could work on a Mac. Does anyone have any idea what this could be and what I could do to make it stop? I haven't seen even a hint of anything slowing down or acting strange on my computer, but they say I need to get it fixed before they will let me back onto the network. Any ideas? Thanks.
