“The dangerous Internet Explorer [ exploit ]
Short summary of action items:
If anyone you know still uses IE 6 or 7 – for any reason – get them to upgrade ASAP. IE 8 might be vulnerable on XP, likely not on Windows 7 at default security settings (although if the end-user has lowered security defaults on the Internet Zone, or turned off Protected Mode, then all bets are off.)
Firefox 3.5.7 with current versions of the NOScript + Adblock Plus plugins installed and properly used by the end-user is a fairly safe browsing tool.
Not browsing the web until a hot-fix is released is not likely a satisfactory solution, but tempting none-the-less . . .
