MBAM scan says that yupdate-exec-yabrowser.exe is a trojan--seems to be a Yandex browser exe so not sure if trojan

[mkb]

I ran an MBAM scan today before I did my backup, which I always do. It flagged a file in the temp directory (Windows 7 x64) as being a trojan. The files name is "yupdate-exec-yabrowser.exe".

I let MBAM delete it and reboot my PC.

The exe seems to be part of Yandex Web Browser which I installed several weeks ago. I'm not sure if it was supposed to be flagged as a trojan or not? Maybe someone here on the forums can enlighten me?

I'm running a full-scan now (after Chameleon was ran and removed trojan) just to be extra safe. Then I plan on removing the Yandex browser as a precaution.

Any help would be appreciated as I would really like to use the Yandex browser. I've attached the log file showing the files name and that it was successfully deleted by MBAM.mbam-log-2012-11-03 (15-46-56).txt

UPDATE: after running the full scan it then found this C:\Users\michael\AppData\Local\Yandex\Updater\yupdate-exec.exe (Trojan.Backdoor) -> Quarantined and deleted successfully.

After rebooting I removed the Yandex browser to be safe. Then rebooted. Then ran MBAM Chameleon once more and it came up clean, so I proceeded to do my backup.

Would really like to use Yandex browser as long as it is not a trojan but a legitimate process.

Here's the log:
