Most apps on Android behave like a malware. The most annoying ones are those who randomly take over the screen and play ads with annoying music and you have no way to close it quickly and you don't know which app is displaying those. Only solutions so far is to actually disable apps one by one and see if the problem appear. I think Google should remove all apps that do that. My friend's phone who is not IT literate, essentially looks as the IE6 back in the day.
