Mihai Grigorescu, virus analyst at Avira. He added that PUA/CryptoMiner.Gen is a generic detection, so there are a lot of different malware detected by this name.
There are two important words here – Cryptominer and PUA. As a cryptominer, this uses your device’s extra computing capacity to do the blockchain calculations needed to generate cryptocurrencies (for someone else). Second, it is considered a PUA or Potentially Unwanted App because it is not directly malicious.
Probably not, but it will damage your mood … As cryptominers increase CPU use, they do increase energy use and potentially can shorten the lifespan of the CPU unit. But, the real cost is your time. Just think of the time spent waiting for the device to start-up, slower operation of simple things like spreadsheets, and those long periods of shutting down – that’s where the real cost is.
However, a PUA app may bring more unpleasantness to your life. PUA apps are known to bring in a host of other PUA apps and dubious advertisements. There is a risk that this app will upset your usual user online experience.
As my child has demonstrated, it is important to do regular scans of your device. In addition, rooting out malware is easier when you – or your children — are not using the device as the admin. By running as a separate user, with fewer privileges than the admin, you make it a bit more difficult for malware and annoying cryptocurrency apps to infiltrate your device.
