Umm, no - so, please, those of you who are saying "use Firefox" to avoid the scareware, please stop.
What about Firefox with the NoScript extension?
Firefox may be safer with the NoScript extension, but so is IE if you turn off scripting. It's horses for courses - in fact, IE could be said to be preferable because you don't need to go out and find an extension to turn off scripting. In any event, my focus is what happens to users running their browsers with default settings, and no extra protections. Invariably the advice I see given is 'use Firefox', not 'use Firefox, oh and don't forget to install NoScript, and make sure you patch, oh and don't forget about all those third party applications out there that are being targeted - Quicktime, Java, etc'.
Firefox with Adblock Plus also blocks this.
