I did a stupid thing yesterday. I downloaded an icon pack APK file on my computer to upload to my mobile. Anyway, the thing is, when I double clicked on it, BlueStacks (Android Emulator) opened up, and Avast started giving me lots of warnings about BlueStacks accessing Trojan URLs (it blocked them of course).
Now, the thing is: I scanned the APK file both in Malware Bytes Anti Malware and Avast (and even Malware Bytes Anti Rootkit), and it showed no virus or malware found. But when I try to attach the the same APK file as a Gmail attachment (which I read on the net detects viruses, which is why I tried it), Gmail gives me a "Virus found" error.
So, my question is how come such reliable antivirus / anti-malware programs like MBAM and Avast didn't detect the virus but Gmail did? And more importantly, (though I have deleted the APK file in question from my computer) is my computer safe? Or has a rootkit / trojan been installed?
