Weeks ago, I downloaded minergate and it was CPU super consumer. I deleted it and as I said the "Web Content" process is related to the website.
'Related' doesn't mean it is.
This is serious accusation to the well known site like wolfbet, you better have a strong valid proof instead speculative one.
Mind to check your computer temperature at the ilde position? How much it shows and compare it to when you running those autobets ? Do it multiple times and you might can be more sure with what you accused.
I'm not denying there's a cpu mining attempt, there's a lot of suspicious websites that using its visitors to mine through their cpu but this one just lack of evidence.
