FORTUNE -- As a long-time Apple (AAPL) user who doesn't spend much time worrying about viruses, trojans and other malware, I've never had a lot of confidence in the reports issued periodically by computer security companies. They always seemed to be in the protection racket, trying to scare users into buying their anti-viral software.
But a pair of recent reports got me thinking.
The first, from McAfee -- now an Intel (INTC) company -- shows an pretty astonishing rise in malware designed to attack mobile devices, from 792 samples in 2011 to 36,699 in 2012.
The second, tangentially related report comes from Citrix Systems (CTXS), which estimates the adoption rate of mobile platforms in business by tracking their enrollment in cloud services.
Given what McAfee has discovered about mobile malware, it's perhaps not surprising that some enterprises might think twice about letting their employees conduct business in the cloud with Android devices. According to Citrix, 58% of enterprises worldwide were deploying Apple mobile devices in Q4 2012, up 2 percentage points from the previous quarter. Android, at 35%, lost 2 points. Microsoft (MSFT) Windows mobile was flat at 7%.
In North America and Asia the preference for iOS was even stronger: 62% and 75%, respectively.
In Europe, the Middle East and Africa, by contrast, iOS penetration dropped (to 43% from 56%) and Android increased 11 points to 36%.
But what gave me pause was the Citrix chart (below) that showed mobile platform adoption rates by vertical industry. I can see why the user-friendly iOS platform might be preferred in environments in which mobile users engage customers one-on-one, such retail, restaurants and real estate.
But is it really a good idea to be issuing malware-friendly Android devices to field workers in utilities, healthcare and communication services? Citrix was asking the same thing. See Enterprise Mobility Cloud Report Q4 2012.
Chart of the day: Mobile threats by platform, 2012
FORTUNE -- Phil Schiller, Apple's (AAPL) ebullient senior VP for marketing, was doing his thing on Twitter Thursday, alerting his 67,866 followers that Google's (GOOG) Android platform accounted for 79% of all mobile malware in 2012.

The programming platform Oracle inherited from Sun continues to plague Apple
FORTUNE -- "Java's not worth building in," Steve Jobs told the New York Times' John Markoff in 2007. "Nobody uses Java anymore. It's this big heavyweight ball and chain."
To Jobs' regret, Java did not disappear. The write-once-run-anywhere programming platform that Sun Microsystems developed and Oracle (ORCL) inherited continues to drag Apple (AAPL) down.

Two malware attacks illustrate the dangers of a wide-open development environment
FORTUNE -- Developers often complain about the hoops Apple (AAPL) makes them jump through to get their wares into the iOS App Store. But the company has its reasons -- besides its 30% cut of the revenue -- and one of them was illustrated by the warning issued Friday by the FBI's Internet Crime Complaint Center (IC3).
"The IC3 has been made aware MOREPhilip Elmer-DeWitt - Oct 15, 2012 11:55 AM ET
After a series of Java security updates, Apple quietly releases an (invisible) removal tool
In a perfect world, there would be no computer viruses, worms or trojan horses -- and for most of Mac OS X's first 10 years it was blessedly malware-free.
In the world as we would like it, Apple (AAPL) would have used that decade-long grace period to prepare for the day when its flagship operating system got hit -- as MOREPhilip Elmer-DeWitt - Apr 14, 2012 11:41 AM ET
Having written several times -- and taken a lot of heat from PC users -- about the relative security of Apple's (AAPL) operating systems (See Why are there no Mac viruses), I feel obliged to report that Mac OS X is under what appears to be the most serious malware attack to date.
According to a report posted MOREPhilip Elmer-DeWitt - Apr 5, 2012 8:08 AM ET

Biggest savings on Macs. Best deals on accessories. But beware the malware.
Apple (AAPL) posted its Black Friday sale prices at 12:01 a.m. Pacific Time Friday and they were exactly as rumored.
The savings on Apple-branded products range from a high of 15.94% on $69 accessories like the Magic Trackpad to 7.02% -- less than the sales tax in 25 states -- on the $299 Time Capsule 2TB.

Believe it or not, the author of Ed Bott's Microsoft Report is doing Apple a favor
It's easy for Apple (AAPL) aficionados to take umbrage at Ed Bott's recent series on ZDNet about a piece of malware called Mac Defender.
