PUA:Linux/CoinMiner!MTB — CoinMiner PUA Removal

Written by Wilbur Woodham
PUA:Linux/CoinMiner!MTB is a detection name used by antivirus software to identify potentially unwanted applications (PUA) on Linux systems that are involved in cryptocurrency mining activities without the user’s consent or knowledge.

PUA:Linux/CoinMiner!MTB specifically refers to a specific variant or instance of a Linux-based coin miner. Coin mining, also known as cryptocurrency mining, is the process of validating and recording transactions on a blockchain network while simultaneously generating new cryptocurrency units as a reward.

Any kind of malware exists with the only target – gain money on you. And the developers of these things are not thinking of ethicality – they utilize all possible tactics. Stealing your private data, getting the payments for the ads you watch for them, exploiting your system to mine cryptocurrencies – that is not the complete list of what they do. Do you like to be a riding equine? That is a rhetorical question.

What does the pop-up with PUA:Linux/CoinMiner!MTB detection mean?

The PUA:Linux/CoinMiner!MTB detection you can see in the lower right corner is displayed to you by Microsoft Defender. That anti-malware program is good at scanning, but prone to be generally unstable. It is defenseless to malware attacks, it has a glitchy user interface and bugged malware clearing features. Therefore, the pop-up which says concerning the CoinMiner is just a notification that Defender has actually found it. To remove it, you will likely need to make use of a separate anti-malware program.

Is PUA:Linux/CoinMiner!MTB dangerous?

I have already mentioned that PUA:Linux/CoinMiner!MTB PUA is not as safe as it pretends to be. The “legit and valuable” tool may unexpectedly unveil itself as a downloader trojan, spyware, backdoor, or coin miner virus.

That still does not imply that you need to panic – perhaps, this nasty thing has not succeeded to do negative things to your computer.

The exact harm to your system may be caused not just due to the malware injection. A large share of questionable programs, like the CoinMiner app is, is just poorly programmed. Potentially, their actions are rather helpful than pointless if done on particular system setups, however, not on each one. That’s how an uncomplicated system optimization application may trigger mayhem with constant BSODs on your system. Any kind of interruptions to the system registry are risky, and they are a lot more unsafe if done with such programs.

How did I get this virus?

It is hard to line the origins of malware on your computer. Nowadays, things are mixed, and distribution ways used by adware 5 years ago can be used by spyware nowadays. But if we abstract from the exact spreading tactic and will think of why it works, the explanation will be pretty simple – low level of cybersecurity knowledge. People click on promotions on strange sites, open the pop-ups they get in their browsers, call the “Microsoft tech support” assuming that the scary banner that says about malware is true. It is very important to know what is legitimate – to avoid misunderstandings when attempting to find out a virus.

Nowadays, there are two of the most common ways of malware distribution – lure emails and also injection into a hacked program. While the first one is not so easy to stay away from – you should know a lot to understand a counterfeit – the 2nd one is simple to handle: just don’t use cracked applications.
