NortonLifeLock is facing complaints for bundling a hard-to-delete cryptocurrency mining tool into its antivirus software

The company announced the cryptocurrency miner in June as a useful way for Norton 360 users to earn extra cash from their idle graphics card. The tool, dubbed Norton Crypto, mines Ethereum and gives users an 85% cut. The rest goes to NortonLifeLock.  

However, the cryptocurrency miner is now facing backlash after a few Twitter users noticed that the Norton 360 software force-installs the mining tool on PCs through a program called NCrypt.exe, which is difficult to uninstall.

The tweets triggered some users to condemn the company for installing the alleged bloatware. Meanwhile, others are wondering why NortonLifeLock is encouraging users to waste electricity through the Ethereum mining. 

“Norton is pretty much amplifying energy consumption worldwide, costing their customers more in electricity use than the customer makes on the mining, yet allowing Norton to make a ton of profit,” tweeted security researcher Chris Vickery. 

In a statement, NortonLifeLock notes the tool is off by default. “Norton Crypto is an opt-in feature only and is not enabled without user permission,” a company spokesperson told PCMag. “If users have turned on Norton Crypto but no longer wish to use the feature, it can be disabled through Norton 360. Additional information can be found on our Norton Crypto FAQ page."

It’s also important to note the cryptocurrency miner only works on PCs with AMD or Nvidia graphics cards and at least 6GB of video memory.

Nevertheless, NortonLifeLock declined to say whether the company will make it easier to remove the NCrypt.exe program for customer systems. In the meantime, a company employee posted a workaround that involves disabling the “Norton Tamper Protection” function in the antivirus program’s settings, after which you can delete the NCrypt.exe program.

My Experience

I've been a journalist for over 15 years. I got my start as a schools and cities reporter in Kansas City and joined PCMag in 2017, where I cover satellite internet services, cybersecurity, PC hardware, and more. I'm currently based in San Francisco, but previously spent over five years in China, covering the country's technology sector.

Since 2020, I've covered the launch and explosive growth of SpaceX's Starlink satellite internet service, writing 600+ stories on availability and feature launches, but also the regulatory battles over the expansion of satellite constellations, fights with rival providers like AST SpaceMobile and Amazon, and the effort to expand into satellite-based mobile service. I've combed through FCC filings for the latest news and driven to remote corners of California to test Starlink's cellular service.

I also cover cyber threats, from ransomware gangs to the emergence of AI-based malware. In 2024 and 2025, the FTC forced Avast to pay consumers $16.5 million for secretly harvesting and selling their personal information to third-party clients, as revealed in my joint investigation with Motherboard.

I also cover the PC graphics card market. Pandemic-era shortages led me to camp out in front of a Best Buy to get an RTX 3000. I'm now following how the AI-driven memory shortage is impacting the entire consumer electronics market. I'm always eager to learn more, so please jump in the comments with feedback and send me tips.

The Best Tech I've Had:

  • My first video game console: a Nintendo Famicom
  • I loved my Sega Saturn despite PlayStation's popularity.
  • The iPod Video I received as a gift in college
  • Xbox 360 FTW
  • The Galaxy Nexus was the first smartphone I was proud to own.
  • The PC desktop I built in 2013, which still works to this day.
