=============================================
Protect yourself from the latest CryptoWhatever
Hardly a day goes by that I don't hear a story about someone hit by
the latest version of CryptoLocker. On systems that have sensitive
data — which is almost every Windows PC I own — I always ensure that I
have a recent, full backup. For small-business systems, you can use
products from Microsoft or third-party backup tools such as Acronis

Keep in mind that the bad guys are getting smarter and are disabling
Windows' shadow file copies. A full backup will mean you never have to
pay a ransom for your data.
Make sure you have extra protection on machines that are more critical
and thus at higher risk. The CryptoPrevent toolkit (site

The one 'problem' with this, or any other kind of prevention tool is
that
attack vectors change, so CryptoPrevent from last year might not work
against the new approach used by this year's CryptoLocker. But, the
installation method used by the original c-Locker trojan was pretty
big and
the c-Prevent author's explanation certainly justifies the cost to
block
that path, in my opinion.
I might be getting jaded (ha!) but software reviews seem to be more
advertorial than editorial these days...so unless a software company is
ready to buy some click-through ads...
True. All reviews ought to be considered with a grain of salt. I saw
the professional "reviewers" move in and take over Amazon a decade
ago, and it's clear that some of the "review" sites are not
journalistic efforts as much as advertising sites.
There aren't a lot of "general" computing sites left, but I follow a
few security sites (like isc.sans.edu) that tend to be pretty good at
reporting the current problems and prevention, if any.
And now, of course, my Google-fu kicks on, and I find a couple good
write-ups:
