"New MacGuard malware variant gets slightly easier to install"
In this case, of course, "easy" is a bad thing.
The executive summary is that the necessity for the user to provide the system password has been removed; this means one fewer stopping points. Note that this is still not as bad as some of the worst stuff on Windows; one must still run the installer (or permit it to be run automatically by the browser that downloaded it--un-check that setting!) AND one must click at least one of the installer's buttons to complete the installation.
The notification about this new form of Mac Defender, now called "MacGuard" came from a security company that sells anti-malware software for Macintosh. I am not recommending that anyone purchase that product.
As before, I am recommending that we pay attention to what's happening on-screen (operating computers on auto or on insufficient sleep is not good), and then not worry too much. More information is @ LifeHacker.
(I am saving my own rapture for the next iPod iteration. I expect that rapture will not disappoint. )
