What is TrojanDownloader:PowerShell/MinerDw.B!MSR?
TrojanDownloader:PowerShell/MinerDw.B!MSR is a type of Trojan horse malware that utilizes PowerShell scripts to download and execute other malicious files, particularly cryptocurrency mining software. This particular Trojan is designed to secretly install cryptocurrency mining software on the infected system without the user’s knowledge or consent.
Once it infects a system, TrojanDownloader:PowerShell/MinerDw.B!MSR runs PowerShell commands to connect to a remote server controlled by cybercriminals. It then downloads and executes the cryptocurrency mining software, which utilizes the infected system’s computing resources to mine cryptocurrencies like Bitcoin, Monero, or Ethereum. The mining process consumes significant CPU and GPU power, leading to increased system resource usage and degraded performance.
Cryptocurrency mining is a resource-intensive process, and when run without the user’s knowledge, it can significantly slow down the infected system and cause it to overheat. Additionally, the excessive mining activity may result in increased electricity consumption, leading to higher energy bills for the user.
It is crucial to protect your system from such threats by using reputable antivirus or anti-malware software, keeping your operating system and software up-to-date, and being cautious when downloading and installing files from unknown sources. Regular system scans and security updates help to detect and prevent the installation of TrojanDownloader:PowerShell/MinerDw.B!MSR and other malware.
The primary goal of TrojanDownloader:PowerShell/MinerDw.B!MSR is to generate revenue for the cybercriminals by using the infected systems to mine cryptocurrencies. This type of malware can be distributed through various means, including malicious email attachments, compromised websites, or software downloads from untrustworthy sources.

As I have specified previously, non-harmful malware does not exist. And TrojanDownloader:PowerShell/MinerDw.B!MSR is not an exception. This virus changes the system settings, edits the Group Policies and registry. All of these elements are crucial for correct system functioning, even in case when we are not talking about PC security. Therefore, the virus which MinerDw contains, or which it will inject after some time, will try to get maximum revenue from you. Cybercriminals can steal your personal data, and then push it on the Darknet. Using adware and browser hijacker functions, embedded in TrojanDownloader:PowerShell/MinerDw.B!MSR virus, they can make profit by showing you the ads. Each view gives them a penny, but 100 views per day = $1. 1000 victims who watch 100 banners per day – $1000. Easy math, but sad conclusions. It is a bad choice to be a donkey for crooks.
How did I get this virus?
It is hard to trace the sources of malware on your PC. Nowadays, things are mixed up, and distribution tactics chosen by adware 5 years ago can be used by spyware these days. But if we abstract from the exact spreading way and will think about why it has success, the reply will be pretty uncomplicated – low level of cybersecurity knowledge. Individuals press on advertisements on odd sites, click the pop-ups they receive in their web browsers, call the “Microsoft tech support” believing that the weird banner that states about malware is true. It is essential to recognize what is legitimate – to prevent misunderstandings when trying to determine a virus.
The example of Microsoft Tech support scam banner
Nowadays, there are two of the most common ways of malware spreading – bait emails and injection into a hacked program. While the first one is not so easy to stay away from – you must know a lot to understand a counterfeit – the second one is simple to handle: just don’t use hacked programs. Torrent-trackers and various other providers of “free” applications (which are, actually, paid, but with a disabled license checking) are just a giveaway place of malware. And TrojanDownloader:PowerShell/MinerDw.B!MSR is just among them.
