the Confickered about U.K. parliament computers

Are you so naive and arrogant to think you know what's going on in my head about U.K. parliament computers get Confickered?
Servers across the internet run Linux. Actually, the majority of servers run Linux in one form or another. Yet, Windows has more malware written for it. It's a fact that every OS has vulnerabilities. It's a fact that every browser and every piece of software has vulnerabilities just because of how imperfect the designer of that software are.
There are enough reasons to write exploits for Linux just in how many servers there are, yet nothing has been written, even on a small scale, that will run.
Besides, the EU hates MS. That's enough of a reason to stop using Windows in and of itself. By the way, try doing a little research into Linux vulnerabilities before you leave a comment. Know what you're talking about and certainly start reading comments for what they are rather than what you think they are.
It's a little of both actually. The hotfix was made to stop the installation in the way it originally manifested. Now it's possible to get infected with a fully patched machine through a USB drive as well. I'd think Parliament would have switched to Linux by now.
