+Omaha team members and TPM

Can you help us take a look at these reports? Are there any additional logs we can collect?

The same problem exists in the Turkish Google Product Forum.

Sorin, can you redirect? I ganesh@ is looped in already.

If possible can we get these logs from users please :

Omaha log            : C:\programdata\google\update\log
Chrome Installer log : C:\Users\<username>\AppData\Local\Temp\chrome_installer

I tried the following after installing Chrome on a fresh Windows 10 x64 machine:
* Uninstall Chrome. Reinstalling works fine.
* Manually delete the Google folder. Reinstalling works fine.
* Use Revo Uninstaller to uninstall Chrome, and delete all subsequent entries that Revo found. Reinstalling works fine.
* Use MalwareBytes to scan the machine, then uninstall Chrome. Reinstalling works fine.

This is mostly international users that started reporting this starting May 12. And malware is a common theme in many of the reports.

I wonder if this issue has something to do with WannaCry, which started happening around May 12 as well.

Melody, can we ask users to give us a ProcMon log? Here are the steps:

* Download ChromeSetup.exe. Do not run it yet.
* Install ProcMon from https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx.
* Run ProcMon.
* Run ChromeSetup.exe.
* Stop capturing events in ProcMon by switching to ProcMon and hitting Ctrl+E.
* Ctrl+S in ProcMon to save the ProcMon log.
* Send us the procmon log.

I've just tried to repro a few ways on my Win10 Creator's Update machine; no dice. Thinking maybe it was related to a non-EN locale, I tried the FR installer -- still worked fine. The next step if we can't get reliable repro steps would be to get Omaha and Chrome logs and/or the ProcMon log as above.

ProcMon is our best bet at this point. The Omaha installer is likely bailing out early (hence the no UI), and the Chrome installer does not get a chance to run.

I am suggesting the ProcMon Log in Spanish Forum : https://goo.gl/4DTR2U , When I get an answer I'll come back

Could be related to the Big Farm Virus:
http://www.tomsguide.com/answers/id-3411812/weird-virus-malware-rid.html

"Basically what it does is install Chrome and Firefox even though I already have both in a different directory, and it slows my PC to a crawl."

and later:

"I think I managed to somehow erase the virus by using Malwarebytes Anti-Rootkit but I cant install google chrome anymore...."

And another fellow apparently has a workaround:

"I had this problem too and maybe i get rid of it. First of all, delete the folders of the FAKE Firefox and Chrome. Then i uninstalled the REAL Firefox and Chrome.
-After i go to the APPDATA folder (Windows key + R -> %APPDATA%), in the folders Local and Roaming i find some files and folders relate to the malwares, like the folder firefox (not Mozilla Firefox), Bagsarah and such.
-On the Folder 'AppData/Local' i cleaned the Folder Temp.
-After all this i executed 'services.msc' (Windows key + R -> services.msc) and find the entry for 'InstallService/firefoxDL' and 'Update Service/firefoxU' (these are the little scumbags that act like the firefox updater to install all the other garbage), then double clicked and deactivate.
-I also run regedit and using the find tool, search and delete all 'firefoxU'(look out to don't delete any firefoxURL) and 'firefoxDL' entry.
-Reboot and reinstalled the Firefox and/or Chrome. Maybe this will help."

Hi, An user sent a ProcMon Log in This Post: 
https://productforums.google.com/d/msg/chrome-es/IicU_9wGvzA/TfXVn5s6BAAJ (Answer with Google Drive Link) , Check this please.

I do not see anything useful in that log. Did the user try to run ChromeSetup.exe? ChromeSetup.exe does not show up in the log at all.

Ok. 3 user's sent a ProcMon Log now, check post: https://productforums.google.com/d/msg/chrome-es/IicU_9wGvzA/TfXVn5s6BAAJ , "Jonathan Olarte" , "Julian Laurenzano" and "Eloy Garcia(Log updated)"

Ok, this appears due to a malware infection. Users need to find and delete this key:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\GoogleUpdate.exe\Debugger

More details to follow...

I got a few hits for IFEO\GoogleUpdate.exe: [Debugger] 324095823984.exe, here is the most relevant forum thread:

Malware like MIO.exe, WinSnare, Negerle, BIT.exe, as well as fake Chrome. - Virus, Trojan, Spyware, and Malware Removal Logs
https://www.bleepingcomputer.com/forums/t/646806/malware-like-mioexe-winsnare-negerle-bitexe-as-well-as-fake-chrome/

+ a couple of others FYI, it looks like some malware is using Image File Execution Options to disable Google Update and (by extension) Chrome installs.

Some ideas:

Could we please ask users to delete the following key and then try running ChromeSetup.exe?:
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\GoogleUpdate.exe

If not, a reasonable suggestion (without endorsing FRST necessarily) would be to have these folks run the Farbar Recovery Scan Tool as per the instructions here:

Hi, the users deleted the key and chromesetup.exe was successfully run! It works , Thank's ! 

Good to hear that. Please have the users unshare the log files. Thank you!
