There have been a number of these vulnerable driver detections, not just this one (other similar topics in the forum).
The drivers can be vulnerable to bring misused, as stated in the screenshot.
As the screenshot states you can add an exception which could put your system at risk
https://www.google.co.uk/search?q=wr64.sysFrom one of the hits in this search I get this:
WR64.sys is a system file that is part of the Windows operating system. It is typically located in the Windows\System32\Drivers folder and is used to support 64-bit system functions. This file is essential for the proper functioning of the operating system, and it should not be deleted or modified.
Given this is in a different location within the google folder is somewhat suspect, (no idea why it would be here and if it is legit or not.
So why it would be needed in the google\libs\ sub folder given this is meant to be a legit windows driver why wouldn't google use that?
