If you install security updates regularly, your risk of being affected by a drive-by download is virtually zero.
The overwhelming majority of malware is installed by the victim, who is fooled by social engineering.

The "its YOUR fault" implications of these statements is a bit exaggerated.

Alureon (aka Zlob) is a data-stealing Trojan found mostly in the enterprise space. It dates all the way back to March 2007.

Alureon and Zlob are not even close to the same. Zlob is a long dead fakealert trojan that hijacked your browser to show fake error pages (loaded with rogues that would "fix" the "problem") and also directly installed the rogue of the month. Alureon is much better known as TDSS and is a powerful rootkit that uses patched drivers, MBR load points and can even infect through the self protection built into 64 bit versions of Windows. Zlob was usually installed via fake codecs but Alureon/TDSS uses just about every known method including exploits, paid trojan delivery services, fake cracks/keygens and yes even fake codecs. Zlob was mostly a home user problem and Alureon is not much different. Neither would be considered an enterprise targeting trojan.

Even a noob that never has done any research on malware ever could have used google to fact check that one and see that it is all wrong.

Thanks Bruce: for guiding us in right direction. I don't understand why these bloggers mislead general public?

There is no way this is intentional, he just does not know anything about malware beyond a few soundbites and buzz words.

I think this is the case with a lot of reporters/bloggers/writes they do some quick research and find anyone that is willing to say they are an expert to seek advice without checking the facts... ;)

I didn't even read the full thing and could tell whoever wrote it doesn't have a clue what they are talking about. Not confident on anything, but 35% accuracy of the blog.

Browser vulnerabilities also play a role.

Like Bruce said it's TDSS rootkit. Any actual in depth research would tell you this.

Even a quick Google search is enough for this one.

Wasn't it that Ed Bott guy who wrote that misleading anti-Firefox article, too?

Edit: Aha, found it: http://www.zdnet.com/blog/bott/why-internet-explorer-will-survive-and-firefox-wont/3064

He's a funny guy. Haha.
