So ive had this android phone for abt 2 yrs now (v 4.4) and some thing just pops up in the browser (eventhough im not using the browser at that time) and open this url http://clinkadtracking.com/tracking?camp=10001833&pubid=565& . It just randomly shows up when im watching youtube, playing games or texting. I ve checked my device woth multiple AVs now and says there's no problem, i even reformatted my device and its still the case. Sometimes, it even downloads app (apus launcher, msg center, settings, my apps - all of which pops up ads on the screen after install) and install it without any of my permission. What do you think guys is the problem?
