Bitcoin Virus removal instructions
What is Bitcoin Virus?
Bitcoin Virus is malware and a potentially unwanted program (PUP) designed to mine Bitcoin cryptocurrency without permission. Cyber criminals use this malware to generate revenue by stealthily misusing system resources. In most cases, it infiltrates systems without users' consent. As well as mining cryptocurrency, Bitcoin Virus might proliferate other malware and gather sensitive data.
Mining cryptocurrencies has become very popular in the last few years - the most widely used and expensive is Bitcoin. 2017 was an extremely successful year for most cryptocurrencies, and Bitcoin was no exception - its cost increased almost 20 times in the last 12 months (from ~$1,000 in January, 2017, to around $20,000 in December, 2017). These successes immediately attracted cyber criminals' attention. Unlike "real" currencies (dollars, euros, etc.), Bitcoins are not managed/manufactured by any bank. Users "generate" them by employing specific hardware to solve mathematical problems. The entire process is called "mining". Although, at time of writing, the most powerful mining devices are ASICs, currencies can also be mined using regular computer components (such as CPU and GPU). This where the cyber criminals step in - they have developed software (Bitcoin viruses) that stealthily mine Bitcoins in the background of home computers. The application is hidden and, therefore, users are unaware of these illicit background processes. They do, however, experience a significant reduction in overall system performance (mining utilizes virtually all system resources). The more mining of Bitcoins takes place, the harder it is to find solutions to the mathematical problems. Furthermore, mining with conventional computers requires extensive energy and cooling, and is inefficient (maintaining the hardware and paying electricity bills does not make the process viable for criminals). This, however, is not the criminals' concern and so they generate revenue by stealthily employing thousands of home computers, the users of whom are unsuspecting.
There are many variants of malware-type applications that stealthily mine cryptocurrencies (e.g., COINMINER). As mentioned above, cyber criminals do their best to hide these applications. In most cases, they do not appear in any lists of installed applications, however, since these applications make extensive use of resources, they can be detected by monitoring system performance. CPU and GPU usage typically increases to 100%, even though all applications are closed. This makes the system virtually unusable, since applications barely respond/load and continually crash. In addition, some malicious Bitcoin mines perform other unwanted tasks. For example, they install potentially unwanted programs (PUPs) or malware, and even collect sensitive data (keystrokes, URLs visited, etc.) After collecting this information, criminals generate more revenue by misusing the personal details or selling it to third parties. In any case, data tracking can lead to serious privacy issues or even identity theft. For these reasons, Bitcoin Virus should be eliminated immediately. This malware is often concealed, and so you should immediately scan your system with legitimate anti-virus/anti-spyware software and follow the steps below.

As mentioned above, malicious Bitcoin miners often proliferate other PUPs. These programs are also designed to record sensitive information. In addition, potentially unwanted programs typically deliver dozens of intrusive advertisements (coupons, banners, pop-ups, etc.) To achieve this, developers employ various tools that enable placement of third party graphical content on any site. Therefore, displayed advertisements often conceal visited website content, significantly diminishing the Internet browsing experience. In addition, these ads typically lead to malicious websites and/or even run scripts that download and install malware. Together, these programs create a chain of potential computer infections - even a single click on an intrusive ad can result in system infiltration by malware.
Unlike Bitcoin-mining malware, potentially unwanted programs often appear in the list of installed applications and browser extensions. In most cases, they are described to provide "advantageous features", however, the only purpose of PUPs is to generate revenue for the developers. Claims to enable useful features are merely attempts to give the impression of legitimacy. Rather than providing any real value, PUPs display ads and gather private information, thereby posing a direct threat to your privacy and Internet browsing safety.
How did Bitcoin Virus install on my computer?
Bitcoin Virus and potentially unwanted programs are distributed in various ways including intrusive advertising and a deceptive marketing method called "bundling" (stealth installation of third party applications with regular software/apps). Developers know that many users lack knowledge and are careless when browsing the Internet, and using computers in general. Therefore, they hide "bundled" applications within the "Custom/Advanced" settings (or other sections) of the download/installation processes. Many users rush these procedures, skip steps, and click various advertisements without understanding the consequences. In doing so, they expose their systems to risk of various infections and compromise their privacy.
How to avoid installation of potentially unwanted applications?
The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Therefore, be very careful when browsing the Internet and, especially when downloading/installing software. Criminals invest time and resources into intrusive ad design. Most ads look legitimate, however, they are distinguishable, since they redirect to gambling, adult dating, pornography, survey, and other dubious sites. If you experience these redirects, uninstall all suspicious applications and browser plug-ins. In some cases, malware is distributed using spam emails (malicious attachments). Therefore, do not open files received from suspicious email addresses - delete these emails without reading. Carefully analyze each window of the download/installation processes and opt-out of all additionally-included programs. Your software should be downloaded from official sources using direct download links only, since third party downloaders/installers often include suspicious apps (the "bundling" method). Furthermore, use a legitimate anti-virus/anti-spyware suite.
