I've found this (pls note that C reads S in Russian)
I think it's no maleware, it only appears as an update at Play Store by some mistake. I had this update around May/June last year and it messed up my phone totally. The update made all apps force close and I had to make a factory reset.
That time I was on some 2.3.4 build, now on XXLPQ 4.0.3
My phone is factory unlocked and I live in Hungary.
For your own sake, DO NOT install the update and turn off automatic updates.
I'm not sure it's worth remove stock apps just in order not to see it among available updates.
