Symantec talking Mac again

The claim at the beginning of July that they'd discovered a leak in Mac OS X 10.4.6 caused Symantec more trouble than reknown. Actually, everything seems to prove they barely compared the update to 10.4.7 that actually fixed it, to "discover" it.
Here they come again about Mac and security in their Weblog.
To sum up in a brief statement, let's say they justify their warning through concrete examples. It's not that good when you look at these closely though. They first start by complaining about the Mac community desapprobation whenever someone says OS X security might be jeopardized.
This whole thing isn't very convincing, as as professionals they admit (how bad...) they use the word "virus" for everything security leak including spywares and the like... They actually chose to use the one that would frighten people the most!
Yet we have to agree when they claim there's definitely no invincible OS, and that to believe so would be a dangerous illusion.
We'd be the first to inform you about such an issue or potential danger that could end up in losing data or simply control of our machine. We just wish that any warning given was real, and not only concerns things that could lead to something potentially harmful under paranormal circumstances and after an update.
