I can’t find an official link for K.UC (all the links I see are for those sketchy “driver update” sites).
…So I downloaded the zip file, let Windows Defender & Malwarebytes scan it, then uploaded it to VirusTotal. All say it’s clean.
Unpacking the .exe file shows it is indeed a BenQ-related package (some small icons & bitmaps with a CD & the BenQ logo).
It seems safe, but try at your own risk, friend. (Attached zip file to post, rather than uploading to the normal archive location.)
