chrome.exe in Folder C:\ProgramData\Microsoft\Windows Defender\Definition...

Hi,


On my brandnew Win 10 Laptop, i had in the folder C:\ProgramData\Microsoft\Windows Defender\Definition Updates\{...}\*.sys\Application a chrome.exe file and an folder named with the current version of chrome (68.0.3440....). This chrome was also usable for surfing and available for choice in the list for standard apps. I downloaded chrome from google and after installing it, as I saw the chrome.exe in the Definition Update section, i officially deinstalled it in the apps&feature section. After a scan with Windows Defender, the folder and the chrome.exe is no more existing. But the google/chrome registry items can not be deleted and in the list of the standard apps, chrome still remains. Has anybody an idea what this was? Is this normal? Bitdefender says everything is ok (after a system scan). Thanks a lot.
