Someone did 'admit' some time ago that leaving a virus infected computer running was somehow a good idea as it would "sort out their true friends".
I have noticed that I get an increase in viruses at certain times and also on other accounts (eg. non JW email receives viruses from JW accounts). The chances of this just happening are pretty remote I think so I can only assume someone does it on purpose. It typically increases when certain people are having a grumble.
I still intend to introduce a private messaging service here so that people do not expose their emails and can be confident that messages do come from the forum person it says.
In the meantime ... be careful and make sure you have uptodate virus scanning s'ware (you should do this anyway) and be cautious of opening attachments.
