From your 'yum' reference, you've been fiddling with Fedora? I've found that distro way too fiddly to be considered appropriate for your average Windows user. The next release of Ubuntu (due out in April) is probably the closest yet to a good, user-friendly, ungeeky Linux distro which someone currently using XP/Vista could cross over to for general web useage, emailing, word processing, etc and not get their knickers in a twist over. I know what you mean when you say about the endless config files, etc. That scenario is greatly reduced and the PnP thing greatly increased with the latest Ubuntu, which is getting close to 'being there'.
BTW, where you mention networks where you know Conflicker has infected, how did you detect this? Is there a way? If so, I'd like to check my work network out (5 workstations) if this is possible.
