Sure. I think all the info you need is in this screenshot [0].
According to "Matt" [1], It scans the folders related to Chrome. Please do not worry as your data wouldn't be effected by the clean up tool. .. I think reality speaks for itself. My Steam Library just isn't related to Chrome.
It looks like Privdog which was bundled with CIS didn't have the vulnerability (it was an older version of Privdog) but if you downloaded it from the website you would have had the new version (Privdog v3 or later) which would have had the vuln.
If you're running the version of Privdog which came with CIS could you check the version of Privdog ?
Badfish shouldn't have failed for you with the bundled version, but if it did that's probably something that needs to be looked at more deeply.
Neither of those links imply that PrivDog is bundled with those apps. It just mentions it as something you can download.
Edit : Just re-read the linked document. Yes, it does indicate that it's an install-time option. However, I've yet to see confirmation that Comodo software comes bundled with the SSL-intercepting version of PrivDog.
I think you are evaluating 'go' based on feature set rather than the amount of friction a developer experience when using it to develop a good product.
C++ is fantastic but I personally experience far less friction when working with 'go' for most of my task.
The fact that it isn't deployed certainly makes it easier. It has protocol version negotiation built in too, so it can avoid "breaking things" by falling back to TCP if needed.
