I reported last week that German antivirus testing lab AV-Test.org ran some simple tests on a collection of popular free Android antivirus apps and concluded that they're mostly worthless. The report clearly shows that all but one of the tested products was almost completely ineffective.

But were the right products tested? Tech news outlet The Register pointed out that while some of the tested products have millions of users, others with over 10 million were omitted. The free edition of Lookout Mobile Security has 12 million users, and AVG Mobilation (formerly DroidSecurity) has 10 million or more, yet neither was included.

A related article at About.com listed the ten most popular free Android antivirus apps. Only two were among those tested. Here's the list:

AVG Antivirus Free (10,000,000 - 50,000,000 users)
Lookout Mobile Security (10,000,000 - 50,000,000 users)
Antivirus Free (Creative Labs) (5,000,000 - 10,000,000 users)
ALYac Android (1,000,000 - 5,000,000 users)
NetQin Security & Antivirus (1,000,000 - 5,000,000 users)
Norton Mobile Security Lite (1,000,000 - 5,000,000 users)
Web Antivirus (Shiftworks) (100,000 - 500,000 users)
Super Security Standard (100,000 - 500,000 users)
Bitdefender Mobile Security (beta) (100,000 - 500,000 users)
Zoner Antivirus Free (100,000 - 500,000 users)

Vendors Weigh In
Kevin Mahaffey, CTO and co-found of Lookout, didn't disparage the selection of products for testing but instead emphasized the need for true protection. "As instances of malware become more prevalent," said Mahaffey, "it’s critical that mobile security apps detect and block all of these threats to protect users. Mobile devices are becoming the dominant computing platform, which makes smartphones and tablets an attractive target for the bad guys."

Tony Anscombe, Senior Security Evangelist for AVG, felt that the incomplete initial test gave users an erroneous impression. He pointed out that nearly half the smartphones in the world run the Android OS. "It's been well documented by numerous sources," said Anscombe, "that there is an increasing trend in malware on this platform. Smartphone users need put security foremost when using these devices, just as they do when they use a PC with internet connectivity. We, the technology industry and media, need to assist users by educating them that security is essential on these devices… Headlines such as the recent article, that did not cover all the products and technologies available such as AVG's Mobilation, do not assist with this education and can lead to consumers not installing protection or thinking about security and this can leave them vulnerable."

New Test Pending
Fortunately, we won't have to wait too long for a more comprehensive test. Andreas Marx, CEO of AV-Test.org, confirmed that a new round of testing is already in the works. "You can expect a new test report of free and commercial Android security products early next year," said Marx.

Mobile antimalware has been around for years, and for most of those years it was irrelevant. Vendors admitted openly that they simply wanted to have a product already in place at the time mobile malware actually took off. That time is now. Juniper Networks recently reported a nearly fivefold increase in Android malware since July. I'll be extremely interested in the results of that new round of testing.

My Experience

When the IBM PC was new, I served as the president of the San Francisco PC User Group for three years. That’s how I met PCMag’s editorial team, who brought me on board in 1986. In the years since that fateful meeting, I’ve become PCMag’s expert on security, privacy, and identity protection, putting antivirus tools, security suites, and all kinds of security software through their paces.

Before my current security gig, I supplied PCMag readers with tips and solutions on using popular applications, operating systems, and programming languages in my "User to User" and "Ask Neil" columns, which began in 1990 and ran for almost 20 years. Along the way, I wrote more than 40 utility articles, as well as Delphi Programming for Dummies and six other books covering DOS, Windows, and programming. I also reviewed thousands of products of all kinds, ranging from early Sierra Online adventure games to AOL’s precursor Q-Link.

In the early 2000s, I turned my focus to security and the growing antivirus industry. After years of working with antivirus, I’m known throughout the security industry as an expert on evaluating antivirus tools. I serve as an advisory board member for the Anti-Malware Testing Standards Organization (AMTSO), an international nonprofit group dedicated to coordinating and improving testing of anti-malware solutions.

The Technology I Use

Much of the testing I do, particularly testing with real-world ransomware, is just plain dangerous. To perform such tests safely, I sequester them inside virtual machines managed by VMWare Workstation. For cross-platform testing, I use a MacBook Air, a Google Pixel 4, and a 6th-generation iPad.

I rely on my Delphi coding skills to create and maintain small applications. These include programs to check whether an antivirus correctly handled the malware it detected, launch dangerous URLs and record the security program’s reaction, and analyze the malware that I collect for use in testing. I also wrote a tiny browser and text editor for use in testing security apps that have predefined reactions for known products.

I do my writing and research on a Dell OptiPlex desktop, relying on Microsoft Word (my fingers know all the shortcuts). Many of my articles include charts and analysis; Excel is my go-to for those. When work hours end, though, I escape the bounds of Microsoft and Windows. There’s an iPhone in my pocket, I relax with my oversized iPad, and my Kindle Oasis is always loaded with the best science fiction and fantasy.
