Malwarebytes blocks openload streaming videos

how can i use it and prevent it from mining with my pc?

Uninstall it and then run a deep scan on your pc with a good anti-malware tool like Malwarebytes Anti-Malware.

quick google search landed me with this article, maybe check to be sure you're using a legit program (and maybe find an alternative instead?)

It's become a bad habit indeed to push coin miners via web content. I haven't seen it on openload though. In fact it's much more likely that it's a false positive, because openload has been on the blacklist of the MPAA for years. In fact, I would recommend montoring cpu and gpu usuage. If there's a coin miner running on a website, it's very likely you'll know when the cpu spikes up by a few hundred percent. Other than that I found out that addons like "Block miners" (https://mybrowseraddon.com/block-miners.html) or "No Coin" block most miners effectively (since they all have in common that they need to connect somewhere, e.g. coinhive), while still being able to use the related website.
