What is XMRIG Virus?

XMRIG Virus is a completely legitimate open-source application that utilizes system CPUs to mine Monero cryptocurrency. Unfortunately, criminals generate revenue by infiltrating this app into systems without users' consent. This deceptive marketing method is called "bundling". In most cases, "bundling" is used to infiltrate several potentially unwanted programs (PUPs) at once. So, there is a high probability that XMRIG Virus came with a number of adware-type applications that deliver intrusive ads and gather sensitive information.

XMRIG Virus scam

Cryptomining is a process by which computers solve various mathematical equations. For each solution, a fraction of a cryptocurrency coin (in this case, Monero) is rewarded. The more powerful the hardware, the more revenue you generate. In fact, using low-end hardware is inefficient - electricity use is equivalent to, or higher, than revenue generated. Therefore, the entire process is costly and often not viable. To avoid this problem, criminals employ regular users' computers. They infiltrate systems with cryptomining applications (in this case, XMRIG Virus) and generate revenue passively. Note that victims receive nothing in return for the use of their systems. Furthermore, the mining process can take up to 100% of hardware (in this case, CPU) resources. This renders computers unstable and virtually unusable - they barely respond and might crash, leading to possible permanent data loss. In addition, fully-utilized hardware generates excessive heat. In certain circumstances (high room temperatures, bad cooling systems, etc.), mining can damage the hardware - components simply overheat. For these reasons, cryptomining applications that infiltrated the system without permission must be uninstalled immediately (even if they are legitimate).

As mentioned above, there is a high probability that the XMRIG Virus came together with a number of adware-type PUPs. These programs deliver various intrusive advertisements (e.g., coupons, banners, pop-ups, etc.) To achieve this, developers employ various tools that enable placement of third party graphical content on any site. Therefore, intrusive ads often conceal underlying website content, thereby significantly diminishing the browsing experience. In addition, the ads might redirect to malicious sites and even execute scripts that stealthily download and install malware/PUPs. Therefore, even a single accidental click can result in high-risk computer infections. Another important issue is data tracking. Research shows that adware typically gathers various data (e.g., IP addresses, website URLs visited, pages viewed, search queries, keystrokes, etc.) that includes personal information. This data is shared with third parties (potentially, cyber criminals) who generate revenue by misusing personal details. The presence of data-tracking apps can thus lead to serious privacy issues or even identity theft. You are strongly advised to uninstall all potentially unwanted programs immediately.

There are hundreds of potentially unwanted programs, all of which are virtually identical. By offering a wide range of "useful features", PUPs attempt to give the impression of legitimacy and trick users to install. In fact, these programs deliver no real value for regular users - their only purpose is to generate revenue for the developers, deliver intrusive advertisements, and gather sensitive information, thereby posing a direct threat to your privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

A small percentage of PUPs have official download/promotion websites, however, most infiltrate systems without users' consent, since developers proliferate them using the aforementioned intrusive advertisements and a deceptive marketing method called "bundling" (stealth installation of PUPs together with regular software/apps). Developers hide "bundled" programs within "Custom/Advanced" settings (or other sections) of the download/installation processes - they do not disclose this information properly. Furthermore, many users skip these steps and click various advertisements. This behavior often leads to inadvertent installation of PUPs - users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

Careless behavior and lack of knowledge are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet and downloading/installing software. Bear in mind that intrusive advertisements typically seem legitimate, but once clicked, redirect to dubious websites (gambling, adult dating, pornography, and similar). If you encounter these ads, immediately remove all suspicious applications and browser plug-ins. Furthermore, closely analyze each step of the download/installation processes and opt-out of all additionally-included programs. We also advise you to avoid using third party downloaders/installers, since developers monetize them by promoting PUPs. Software should be downloaded from official sources only, using direct download links. If your computer is already infected with PUPs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
