i use firefox so like many others i didn't notice the problem at first. and i don't doubt that hando has plenty of better things to be doing. but at present the board has over 8,000 registered users. if only a quarter of them use IE than you still have 2,000 people.
the initial security breach is probably not worth blaming anyone for, but a great number of people's computers are at risk for almost certain infection, if they have not been infected already. many of these are corporate machines.
hando should have fixed the hole by now. it's possible and fairly probable that he could be taken to civil court for damages due to negligence. no, nobody's putting a gun to your head and making you visit these forums. and again, the initial problem is (arguably) no one's fault except the person who engineered the exploit. and it's not like hando's some scheming corporate type who only answers to the shareholders. but wherever you come from, you have a "duty of care" to act reasonably and appropriately around others, if you know that failing to do so could directly harm them. what we have here is a lot of harm being done to a lot of people over an extended period of time. there is a point where that becomes inexcusable.
i hope this gets sorted out, for the sake of all those who've been infected, all those who've yet to be infected, and i hope that hando realizes he could be risking something bigger than his OS.
the larger lesson, and this is unfortunate, is that the internet is not a safe place. at bare minimum, anyone with a broadband connection needs: a firewall (software or hardware, even just a router is good protection), virus protection, spyware protection, and a browser that's configured for safety. firefox comes like this. but internet explorer can be made secure as well.
