Norwegian browser maker Opera has launched the beta version of Opera 50, the first popular browser to integrate a built-in cryptocurrency-mining blocker.
“Your CPU suddenly working at 100 percent capacity, the fan is going crazy for seemingly no reason, and your battery quickly depleting might all be signs that someone is using your computer to mine for cryptocurrency,” said Opera.
Opera’s cryptocurrency mining protection is part of Opera’s built-in ad blocker. The company has tried to differentiate itself with a range of novel features, such as the ad-blocker and a built-in VPN.
To enable the mining protection, users need to go to Settings or Preferences. The NoCoin (Cryptocurrency) setting can be found in Recommended lists of ad filters in the Block ads page.
“With NoCoin turned on, pages embedded with cryptocurrency mining scripts will be blocked in a similar way our mechanism blocks ads,” said Opera desktop QA Kornelia Mielczarczyk.
In the beta at least, the NoCoin option is enabled by default. The feature works by blocking cryptocurrency mining scripts.
Expect to see more miners silently chewing up CPU resources through your browser.
Stealthy and persistent cryptocurrency-mining malware is hitting Windows machines.
Your PC may be used to find cryptocurrency when you visit websites, with or without your consent.
