That is really strange. I just copied the .apk from my device and ran a scan on it on my Windows machine with ESET. ESET found every part of it to be clean, so then I moved the file to my Linux machine and checked it with ClamAV, which also showed it as clean. Odd.
You took one step ahead of me and submitted it to avast. I'd love to see what it comes back as.
It was only after a recent avast update. It flagged a couple of apps including Google currents and music as issues but everything had been downloaded or updated from the play store. I'm aware of downloading from unknown sources and the possibility of dodgy apps on the play store but I'm sure I didn't dl anything bad.
