BitCoinMiner is a group of trojans that install Bitcoin Miner application. Bitcoins are virtual currency that relies on complex computations. The more people do these computations, the safer the network is from hacking attempts. Due to its nature it is possible to earn small sums of coins by performing these computations. The amount of bitcoins (BTCs) earned is reduced over time, thus it is not really useful to run miners on your own computer without specialized hardware.
However, this is mis-used by malware makers who infect hundreds of PCs in order to run various BitCoinMiners. They gain money much more effectively compared to legitimate ones as they do not have to pay for electricity or computers that perform the calculations. The longer malware mines on infected PCs, the more Bitcoins cyber-criminals get for free.
Older versions of BitCoinMiner like Trojan.Cointbitminer used CPU only. This was very inefficient, thus new versions target gaming PCs that have powerful videocards. These cards perform computations more efficiently, thus one could earn BTCs faster.
Typically, you will not see much of symptoms when infected with Bit Coin Miner. Your PC might be a bit slower than usual, however, the application runs on full power only when you are not using your computer. If you feel that your PC cooler is working harder when you are not working on it, it might be a sign of CoinMiner virus infection.
This infection is not very dangerous alone. However, the important point is that BitCoinMiner got installed on your PC somehow. This can be a sign of serious PC infestation, for example, being part of some sort of Botnet owned by illegal miners. At any time they might re-focus from BitCoins to making money by stealing your banking details or sending out spam. It is advisable to remove the miner and all other infections from your computer.
BitCoinminer : infection or harmless?
Bitcoins have several benefits. Firstly, transactions are very fast and irreversible. This is very attractive for cyber-criminals as they don’t want any charge-backs. Secondly, they are almost-anonymous and it is hard to find the person that owns the wallet with the coins. Thirdly, this currency is not controlled by anyone and any government. All these things make owning Bitcoins interesting for both honest and dishonest people (2).
Antiviruses know about Bitcoin Mining Trojans, and it is easier to detect the Miner (that has to do specific computations) that thousands of possible parasite versions. If you have installed such application yourself and your antivirus detects it, you can leave the application on your computer. It is not dangerous on itself as long as it is properly configured and does not use malware maker wallet credentials for sending money.
You have to clean your PC if you are not sure how BitcoinMiner got installed on PC. It is advisable to use anti-malware program like Spyhunter or Hitman Pro to identify malicious files and delete them. Look for various trojans in detection lists and not the Miner application only.
