I got a little toast pop up just now saying "hello world, PMEasyView!" I just woke up my phone, was in the SugarSync app. I haven't recently installed anything except from the Android Market and Amazon market; nothing named like PM Easy View.
The wording sounds like something I would have written in a development Android app. I don't see any unusual running processes or apps, so I'm wondering if it's dummy code from a real app I own, but I was hoping someone knew for sure. I'm having Lookout scan my phone now.
All I found on this topic was this thread which has no answers.
