The group found that only 80 of the apps could stop even a minimal amount of malware. "Less than one in 10 of the apps tested defended against all 2,000 malicious apps, while over two-thirds failed to reach a block rate of even 30 percent", the lab said in a press release.
It advised that if you want to make sure you are protecting your Android device adequately, stick to apps from well-known antivirus companies.
AV-Comparatives said, most Android antivirus apps were phoney, and many of them seemed to have been created only to display ads or promote a developer's career.
"The main purpose of these apps seems to be generating easy revenue for their developers, rather than protecting their users."
The antimalware apps from the following 138 vendors detected less than 30 percent of the Android malware samples, or had a relatively high false alarm rate on popular clean files from the Google Play Store: 1Machine System Sdn Bhd, actionappsgamesstudio, Amantechnoapps, AMIGOS KEY, Amnpardaz Soft, AndroHelm Security, ANTI VIRUS Security, Antivirus Mobile Lab, antivirus security, appflozen, appsshow, Appzila, Arcane Security Solutions, AS team security phone Lab, asuizksidev, Ayogames, AZ Super Tools, azemoji studio, Baboon Antivirus, bESapp, Best Battery Apps, Best HD Wallpapers APPS, Best Tools Pro, BestOne, Bit Inception, BKAV, Bom Bom, Booster studio Laboratory Inc., brouno, Bulletproof AV, Caltonfuny Antivirus Phone, Cheetah Mobile, CHOMAR, Chromia, Cloud 7 Services, Core Antivirus Lab, CPCORP TEAM: Photo blur & photo blender, CreativeStudioApps, CY Security, Defenx, DefineSoft, DreamBig Studios, DU Master, electro dev, Erus IT Private Limited, Falcon Security Lab, Fast n Clean, fluer-apps.com, Formation App, Free Apps Drive, FrouZa, Galaxy TEAM, GameXpZeroo, GlobalsApps, gndnSoftware, GOMO Apps, GoNext App Developers, Gridinsoft, LLC, handy tools apps, Hello Security, Immune Smart, INCA Internet, infiniteWays007, Islamic Basic Education, Itus Mobile Security, JESKO, jixic, Kolony Cleaner, Koodous Mobile, lempea, LINE, LIONMOBI, Live multi Player Game, Main Source 365 Tech, Mama Studio, MAN Studio, Marsolis Tech, Max Antivirus Lab, Max Mobi Secure, MaxVV, Mob Utilities, Mobile Tools Plus, Mobtari, Mond Corey, M-Secure, MSolutions, MSYSOFT APPS, My Android Antivirus, NCN-NetConsulting, Nepelion Camp, Nisi Jsc, Niulaty, NP Mobile Security, NPC Studios, Omha, Oxic Studio, Pix2Pic Studio, playyourapp, Pro Tool Apps, prote apps, Protector & Security for Mobile, Puce, Radial Apps 2018, RedBeard, Secure Cloud, SecureBrain2, Security and Antivirus for Android solutions, Security Apps Team, Security Defend, SECURITY LAB, Security Systems Lab, SecurityApplock, Sept Max, ShieldApps, SjaellSoft, SkyMobileTeam, Smart Battery Solution & Creative Screen Lock, smarteazyapps, Software Center, Soft War, stmdefender, Systweak Software, TAIGA SYSTEM, Tokyo Tokyo, Tools dev, tools for android, Utilitarian Tools, Vainfotech, VHSTUDIO, Vikrant Waghmode, Virinchi Software, Virtues Media & Application, VSAR, Wingle Apps, Xtechnoz Apps, XZ Game, Z Team Pro.
“We consider those apps to be risky, that is to say, ineffective or unreliable. In some cases, the apps are simply buggy, e.g. because they have poorly implemented a third-party engine. Others detect only a handful of ancient Android malware samples, and allow any apps that contain certain strings, making them likely to pass some quick checks and thus be accepted by the app stores”, the site said.
