This is the same problem as the following thread:

 

http://www.bleepingcomputer.com/forums/t/544970/yikes-possible-gnarly-rootkit-on-my-system-need-some-help/

 

 

Same thing is happening to one of my users.....

Google Chrome is not even installed on the computer, but the (browser).exe process kept popping up with random PIDs and "Google Chrome" as the description.

I found that the process was being run from C:/Users/%USERNAME%/AppData/LocalLow/PerformanceVideo/ServiceDisplay

I ended the processes and deleted the PerformanceVideo folder above and the folder just immediately regenerated.  There was QueryBroadband folder that appeared in C:/Users/%USERNAME%/AppData/LocalLow as well.

Both of those folders remanifest immediately upon deletion.

The QueryBroadband folder contains nearly a duplicate folder structure as the C: drive.....the difference is that all the folders are empty EXCEPT "Local", which contains /Google/Chrome/UserData with cookies and history and other browser data files.

I killed the (browser).exe process yesterday and renamed the (browser).exe in C:/Users/%USERNAME%/AppData/LocalLow/PerformanceVideo/ServiceDisplay to browser.old and up until this morning the rogue process did not come back.

 

The user can't tell me what she clicked or when it started happening.  I know that Chrome has never been installed on this PC (Win7 x64) before.

I have tried a system restore unsuccessfully.

Hello! Welcome to BleepingComputer Forums! :welcome:
My name is Georgi and and I will be helping you with your computer problems.

Before we begin, please note the following:

  • I will working be on your Malware issues, this may or may not, solve other issues you have with your machine.
  • The logs can take some time to research, so please be patient with me.
  • Stay with the topic until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
  • Instructions that I give are for your system only!
  • Please do not run any tools until requested ! The reason for this is so I know what is going on with the machine at any time. Some programs can interfere with others and hamper the recovery process.
  • Please perform all steps in the order received. If you can't understand something don't hesitate to ask.
  • Again I would like to remind you to make no further changes to your computer unless I direct you to do so. I will not help you if you do not follow my instructions.

 

 

 

Please download the latest version of Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatibale with your system. If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

 

 

Regards,

Georgi
