this bloody computer !   what seems to be the problem ?   my computer just crashed again for the third time today !   what were you doing when it crashed ?   i was just opening up an attachment in an email about winning the lottery .   I think that might have been a virus .   oh , no ! I thought it seemed a bit strange .   what kind of computer do you have , a Mac or a PC ?   it's a PC . doesn't everyone have a PC in this office ?   no , some people have Macs now , too .   what's the difference ?   PCs often crash from virus , but it's nearly impossible to get a virus from a Mac .   I didn't know that .   has your computer turned back on yet ?   yes .   did you end up losing any of your work ?   fortunately , I saved my work right before it crashed , so it should be OK .   you should probably call the IT department and have them check your computer for virus .
