Re: The bill for all this...
Bollocks. It all stems from MS old code that to allow people to use computers *easily* they built in things to allow people to do things rather than have a proper security schema. Then came the Internet and multiuser environments, and all they done (and still do) is plumb in new pipes to get around it.
MS never had any security from bottom up - it is all patched and repatched and even repatched - and hence why all the spam mails, scams, and other shite ALWAYS involves a botnet of MS compromised machines.
Stupid OS with stupid users = disaster.
As someone once said:
"Microsoft allowed people to use a computer that shouldn't even be let near a computer".
Also the premise that all computers crash a lot, and is expected.
Personally, I am getting fed-up with the amount of crap I get hitting my mail servers/httpd servers from bloody compromised MS machines. Eventually it looks like I will have to blackwall the whole Internet thanks to MS.
