Ok...I've recently joined the Mac world (from years in Windows). One of the reasons....viruses. Everyone keeps saying to not even bother getting anti-virus software for you Mac...that it's unnecessary or would probably just cause problems with your system. So here are the questions: If a windows virus is sent to someone on a Mac via email, download, or whatever...can that virus be spread to other windows machines via the Mac? I would think that since it's designed for windows it would just kinda die in the Mac OS. Also, do anti-virus software for Macs detect and remove windows viruses? The reason I'm concerned about this is because I don't want to infect other networks/computers....especially my work's network (sometimes I have to work from home).
