I don't know, I go away for a few weeks' holiday and come back to (amongst other things) this mega-thread covering at least 3 of my favourite PC-related hot topics: security, browsers and Linux !
There have been a number of comments in here which are pertinent to other threads around problems caused by poorly protected PCs.
There are evidently a number of folk on this board who have some very good knowledge and maybe a separate thread could be used to reach a consensus on what would be a sensible approach for those less-technical to avoid some of these problems in the first place? If no-one bites the bullet I'll kick off that thread tomorrow (it's 1.30am here so I'm not at my best

)
Oh and for whoever wanted some good things said about Windows 7, I'll say that having tried to find fault ...er I mean test... both the public Beta and RC1 over the last few months, it looks like Microsoft may have got themselves the OS that Vista should have been - stable, efficient, secure and useable.
