Avast was in the new recently as there were reports that google apps were being flagged as malware, and to that effect, the apps were either being removed from devices or were no longer responsive. Users whose devices were running the Avast antivirus applications brought this issue to light and slowly, the update gained traction, to a point that Avast themselves had to intervene.
In a public apology announcement, Avast said that “its antivirus Software Development Kit (SDK) for Android was incorrectly flagging the Google Quick Search Box as malware on Huawei phones. This SDK delivers the antivirus component of Huawei’s Optimizer app.”
