What's the wierd looking update that's just turned up on my Samsung Galaxy phone?

"MTC (Cyrillic text)" by "OJSC Mobile TeleSystems".

The review section has lots of one-star comments saying its malware etc, but I'd have thought actual malware would look more like something I'd want to install than something wierd in Russian.

Should I be worried? Is this malware or some perfectly normal component buried in the OS that's somehow found its way into public view? Should I install the update?
