chrome.exe suddenly missing, system restores unavailable, and apparently bogus Windows Update -- infected, but with what?

[djohnson]

This morning my wife told me that when she clicked on the Chrome icon on our home computer, it notified here that chrome.exe was missing. I did an MBAM scan, and it found some stuff and apparently removed it... or something (see "2016-05-03 scan results.txt" and "2016-05-03 protection log.txt").

I went into System Restore looking for restore points hoping for an easy fix. It said that System Restore was unavailable and no restores were listed.

Then tonight Windows Update prompted me to install this apparently bogus update: Definition Update for Microsoft Office 2010 (KB3115129) 32-Bit Edition. The support page at the MS site gives a 404: http://support.microsoft.com/kb/3115129

I'm suspicious about the update, so I hid that update to prevent it from installing. It looks like I'm not the only one today who wonders if this is legit: http://www.dslreports.com/forum/r30738305-WIN7-KB-3115129-Published-today-5-3-2016-Important

I ran the FarBar scan and have attached the results as well. I realize Addition.txt mentions that I have μTorrent installed... I just uninstalled it using Windows Add/Remove Programs to meet with the piracy policy for this forum. Please let me know if I need to prove that I've uninstalled it more thoroughly... I ran the FRST scan after uninstalling but with a reboot in between, so I'm not sure why it's still in the list. I'd be happy to do whatever is necessary in that regard... haven't used μTorrent in years.

OK, I figured out what I did wrong with the μTorrent removal. The attached FRST.txt and Addition.txt indicate that it's been removed from the system.

Thanks for any ideas!
