PUP.Optional.Miner is a detection name for a legitimate coin mining tool. However, there is no guarantee that you have installed it by your own wish. If you cannot remember that you have installed any tools for cryptocurrency mining – you are definitely in danger. The possible consequences of an alien coin miner activity are very unpleasant. But if you have set up a cryptomining program – don’t worry, that is just a warning detection. Since coin miners are often used by hackers, they are considered hacktools and often marked as unwanted programs.

PUP.Optional.Miner

The most regular channels where malicious PUP.Optional.Miner examples are injected are:

  • Malvertising on the Web;
  • Banners shown to you by adware;
  • Dubious tools downloaded online – system or registry optimizers, driver updaters, et cetera;

Right after the PUP.Optional.Miner is injected, it starts exploiting your hardware. CPU load, as well as GPU consumption, can reach 80-90%, making all normal tasks impossible. Such high numbers are needed for the exact task – cryptocurrency mining. Mining, i.e. calculating the transaction hash, is a very computationally intensive process. As you could hear, mining is usually conducted on so-called cryptomining farms – special computers that have a specific hardware setup. Mining on a regular PC makes it useless for daily tasks – browsing or modeling. Moreover, such high loads can lead to quick degradation of your hardware elements. Removing the unwanted PUP.Optional.Miner must be your main task.

PUP.Optional.Miner distribution channels.

Spreading of coin miners is oftentimes conducted through malvertising. Malicious banners can be placed by a greedy website owner, as well as shown to you by adware. Adware, exactly, is one of the most popular sources of coin miner injection. People somewhy have a silly habit to click the banners they see online, ignoring the risks this action can carry. Another way of miner injection is through a trojan virus form of injection. When it is disguised as a legitimate program, no one will just think that it can cause such serious problems.

Regardless of the exact way of PUP.Optional.Miner injection, the advice about how to avoid it is pretty easy. Do not click on the banners online – whatever they offer to you, it is too risky. If you see the ad about an attractive deal from a known retailer – better go on its website and check it manually. Also, do not trust the programs from third-party resources. Torrent-trackers, “free” software distribution sites and online forums are the best places to distribute your malware. Be careful online – and your system will be safe.
