You wouldn’t want a stranger stealing your computing power, would you? That’s exactly what’s happening on Macs right now with the Mshelper virus. Gone are the days where MacOS was considered virus resistant. New threats are always being developed, and Apple users are not immune to them. You need to learn more about this virus and how it may be affecting your computer, especially if you’re into cryptocurrencies.
What is Mshelper?
Mshelper malware mines cryptocurrency on your computer without your permission. This virus forces your Mac’s CPU to crunch numbers and to generate digital currency for its maker. It’s already been linked to Bitcoin, Monero, and Litecoin.
Even though crypto prices are dropping, hackers can still make a lot of money by hijacking the CPU power of your computer. A single BTC is currently worth $3,500, LTC is $24.77, and Monero is $44.24. The Mshelper virus can mine these tokens for other people for free using your computer.
But there’s good news. Mshelper is rather poorly designed malware. Because cryptocurrency mining is incredibly CPU-intensive, the virus is easy to detect. Plus, it runs at full power all the time instead of waiting for whenever the machine is idle like other malware threats in its class.
One theory suggests the virus comes from a hijacked Adobe Flash Player installer, but that’s currently unconfirmed. Just because we don’t know where Mshelper comes from doesn’t mean we can’t deal with it effectively.
How Is Mshelper Harmful?
The virus is mostly harmless compared to other viruses. It doesn’t steal personal information or intercept logins. Instead, it:
- Hogs your Mac’s system resources
- Reduces the battery life of your device
- Raises operating noise and temperatures
- Greatly cripples performance
- Degrades your device’s lifespan
Apple will more than likely patch this virus in a future update, but it’s worth checking for it now.
How Can I Check Whether Mshelper is on my Machine?
To verify whether your system’s sluggishness can be attributed to Mshelper, check for its process in your Activity Monitor.
- Open MacOS’s Activity Monitor.
- Click on the CPU tab.
- Organize the list by CPU usage; Mshelper should be near the top.
- Alternatively, organize the list in alphabetical order and search for the name that way.
