This is the same problem as the following thread:
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.
