[X4U] Trojan horse on the Mac?

[Bob Aldridge]

Cable company gave the e-mail of the offending PC's and Mac.

I doubt the cable company too, but I need to prove them wrong on this and
prove to the staff Macs are safe as I professed.

Doing a little checking around I found ClamXav. I'll give it a shot.

Thanks,

--Bob
