Hi Randy: Thanks for the rapid response. >Note that it is highly unlikely that you might unwittingly transfer a >Windows virus to a Windows-using colleague. Windows-only viral e-mail >attachments that you receive can just be trashed, they are easy to spot, >so it isn't at all likely that you will be re-sending them. Looked at that way I can see your point. Unless I actively attach one to an e-mail there is little possibility of it happening. The only ones that ever get a look are those that appear to come from someone I know and then the subject line usually gives it away. > Files that >show up with macro-viruses can be blocked by setting "Macro Virus >Protection" in Word's preferences. Any unknown macro can be deleted in >Word. I have the macro virus protection set already, must admit I didn't realise that unknown macros could easily be deleted. Is this true of Word 2004 as well as Vx? >You aren't going to be a go-between for transfering Windows applications, >are you? So VirusBarrier should be all that you need. The "problem" of >Macs being carriers and spreaders of Windows viruses is a myth >perpetuated by Windows biggots. I'm not a go-between for Windows apps but I do swap Word documents with colleagues. I try to avoid Word as much as I can but sometimes I have no choice. cheers, Chris
