Watch out the Greedy Bitcoin Miners in Your Computer
Does the inexplicably slow speed of your computer ever drive you crazy? Does this make you want to smash it to pieces? If your computer has suddenly slowed down just after you downloaded something (like an HD video player or Flash plug-in), then it is likely that the cause of your problem is not the age of your computer,but an uninvited Bitcoin miner. These miners hijack your computer's resources in order to gather Bitcoins, a valuable e-currency.
Since June, Baidu Antivirus Security Center has been tracking a Bitcoin Trojan variation (named Trojan.Win32.BitCoinMiner.71) spread through advertising downloaders. The Bitcoin Trojan generally uses the same propagation methods as other prevalent Trojans (e.g. fraudulent downloads, malicious email links and attachments, and advertising platforms). According to data from Baidu Antivirus Security Center, a large number of users are currently at risk from this Trojan variation.
According to Baidu Antivirus security experts, high-intensity computing is required to mine Bitcoins with the Bitcoin Trojan, thus consuming a great deal of computational resources. This is why computers infected with the virus are slowed down. Cybercriminals usually try to hijack enough computers so they can group them together to create a supercomputer they can use to mine Bitcoins and reap huge profits.
Currently, Baidu Antivirus users can protect against these Trojan just by enabling the full protection feature. It is recommended that the other users download the latest version of Baidu Antivirus and enable the full protection feature so that Trojan will not be installed.
Inaddition, Baidu Antivirus security experts advise users to download software from official sites. This will allow users to avoid unintentionally infecting their computers with the Bitcoin Trojan via malicious downloaders, which will negatively impact their computers' performance.
