I've been dealing with this problem for about a month. My Samsung Galaxy S4 running Jelly Bean 4.2.2 downloads random files, not applications. I've been able to pinpoint that the files download while I am browsing the web whether it is Google Chrome or the native browser.
The files all have the same format, and when clicked on, I cannot open them. They look like this and show up in the Notification Pull Down Menu, but are not housed anywhere else on the phone:
st (1)
st (2)
and so on...
I'm already at st (48)....
so apparently there's been that many instances of this.
I've used Avast and Lookout to run full scans, and even looked at downloading some Malware applications, but nothing helps. I found a threat with a scan on Lookout after Avast was unable to identify it. I removed the threat, and still getting the random file downloads. Please Help!
