Qihoo 360 was banned from the Google Play store long ago for multiple violations of Google's developer rules including tricking users into installing their app by hijacking the users mobile WebView browser with fake virus warnings.
Qihoo 360 is back doing the same thing only this time using a relatively unknown app developer out of Brazil named Psafe.
Psafe was heavily funded by the Chinese and has been luring novice Android users into installing the "DFNDR" app with fake virus warnings every day since 2013 to the present.
The app itself uses Avast's virus detection engine but is packed with several advertising SDK's and is now charging enormous fees to users account after a brief "trial" period.
The app was harvesting users social media data and could access the SQLite database of WhatsApp and was known for pushing polital ads on the users device.
I had brought the fake virus warning issues up with Avast but nothing was ever done about it other than me getting a lifetime ban from the Avast forums.
Myself and others have also filed numerous complaints to the FTC regarding the app.
Here is a users complaint on the Google Play store reviews from October 9th 2020:
"DO NOT DOWNLOAD! This "antivirus" is, itself, a virus. Well, it's a companion virus to a web-based virus. I'm sure you were directed here from an ad on your web browser saying your specific phone has a virus and you MUST have this SPECIFIC antivirus to get rid of it? It's all a scam. This company MUST be sued ASAP, and all of their products MUST be removed from Google Play IMMEDIATELY. Get another antivirus for your phone. Seriously."
