Researchers at Avast Threat Labs say that more than 100 different low-cost Android devices from manufacturers like ZTE, Archos, and myPhone come with malware pre-installed. Users in more than 90 countries, including the US, are said to be infected. The good news is there’s a fix. According to the report, this adware variant has been in the wild for three years. It’s called “Cosiloon” and was first noticed by Dr. Web in 2016.
