I'll save the coredump, unless severely provoked. I'd still advise you, Charmion, to invest in antivirus measures beyond just not using MS-Windows: some years ago, a botnet was discovered that specialised in hijacking MacOS systems, several hundred of which were found to be in Apple's HQ.

Even UNIX systems (including Linux, and MacOS under the covers) aren't immune, as I found out the hard way at least three times. It just happens that MS-Windows offers the lowest-hanging fruit for the bar stewards, but anybody on any OS can get phished or otherwise victimised.
