The file indicated is a WMI cache file, which is generated on your computer and not shipped with the product.
I am quite certain it is a false positive, since the file is not really executable in any way.
It is a text file, you can open those files in any editor to check, they contain information about the WMI class with some partial HTML around it for display purposes.
Since this occurs on your machine, I would suggest to submit the file to Microsoft for verification:
just to be on the safe side.

Thanks Alexander.
After sending the report, I looked a bit deeper and realised as you pointed out, the file is a local one.
I will submit to MS today.
Thanks for the prompt response.
