A search on my C drive (Win7Pro-64bit, Chrome browser) shows 5 files with the RAVbg64 name. They vary is size from a few thousand to 10MB. I also suspect that one of these is infected or otherwise broken and causing complex and annoying problems. Searching on the Realtek site for RAV brings up NO results!
What's going on here? How do I rid myself of all the RAV files except the one needed, or at least download a secure, functioning version when its mfr. doesn't even list them?
