BIG SURPRISE: Not safe to use Windows today.

So... your posts more or less made sense up till here (or at least up until this one, I couldn't outright say they were baseless, not being too familiar with DEP etc).
But how would you suggest configuring such a firewall? You'd have to write a firewall that understand the HTTP protocol, and knows to block when your machine requests a WMF file. Then of course, someone could make you download via FTP, so your firewall would need to understand that too.
But what if it comes as an e-mail attachment?
Is your firewall supposed to inspect every byte in every packet that comes into your computer, searching for what resembles a WMF file header?
I just can't see such a solution working.
And in all honesty, while I'm not sure about the DEP solution, I'm not even sure if that'll work. I haven't seen any information that suggests that this is a buffer overrun type problem yet. Did you try enabling DEP and clicking on Jason's link btw?

That wouldn't be the case if they were using a hyper-threading processor
I am definitely not willing to say hardware needs to be < 2.5 years old to not be considered obsolete for most desktop use(I use a MUCH older system at home with no problems).

Actually it's quite easy.
Another approach is to only allow you to visit a list of approved sites or restrict access to some sites. I was with a stock trading firm that did it the 2nd way. You couldn't even go to yahoo mail or gmail, etc etc.

It is possible for a firewall to understand HTTP, FTP(This is actually very useful), SMTP, etc, etc. It just takes more processing power. Then again, the data may be encrypted...
I would not call this a solution though. Only a workaround like the steps I posted for disabling the DLL. You are sacrificing part of the product's functionality. It would be like Honda saying not to rev the S2000 > 6,000 rpms to prevent a scorched #1 cylinder. Sure, it may prevent the problem. But that would also be a workaround and not a solution. A solution lets you use the product as it is intended while fixing the defect.

I use iptables, which I'm pretty sure allows me to do pretty much anything. And I know I sure as heck am not going to spend any time trying to figure out how to modify my firewall rules to try and detect incoming WMF files.

Funny how people don't know there asses from the preverbal hole in the ground.
There - I see trees over there.
They're - They're running too quickly.
Their - Funny how people don't know their asses from the proverbial...
Preverbal = not yet containing the ability to speak.
Proverbial = of, or pertaining to, a proberb.
It's happened to me, but it's something everyone should know.
Thank's next time I'll make sure I footnote as well.

You have the mind of a criminal
Yeah you're correct. Didn't think of that
