COINMINER removal instructions
What is COINMINER?
As most of us are aware, 2017 was a very successful year for cryptocurrency miners. The price of popular cryptocurrencies jumped dramatically (for example, in early 2017, Bitcoin was equivalent to ~$1000, while at the end of the year it reached nearly $20,000). Therefore, mining cryptocurrency became even more popular. Cyber criminals also started to partake in this enterprise: to generate revenue, they proliferated malware that stealthily mined cryptocurrency.
As mentioned above, COINMINER is distributed using fake update tools. Therefore, there is a high probability that it will be delivered with various potentially unwanted programs (PUPs). Most of these programs deliver various intrusive ads (coupons, banners, pop-ups, etc.) that conceal underlying content, thereby diminishing the browsing experience. Furthermore, some ads will redirect to malicious websites or even run malicious code that stealthily downloads and installs malware/PUPs. Therefore, clicking them risks further computer infections. Another downside is information tracking. Research shows that PUPs gather various information that typically includes personal data that is sold to third parties. There is a high probability that information tracking will lead to serious privacy issues or even identity theft. Potentially unwanted programs must be eliminated immediately.
Many PUPs offer various useful features, however, since their only purpose is to generate revenue for the developers, these claims are merely attempts to give the impression of legitimacy. Only a small percentage of PUPs provide the features promised - most are useless for regular users. Rather than (or together with) enabling functionality, PUPs pose a direct threat to your privacy and Internet browsing safety.
How did COINMINER install on my computer?
COINMINER and PUPs are typically distributed using the "bundling" method - stealth installation of third party software together with regular (typically free) software. Developers hide "bundled" apps within "Custom/Advanced" settings of the download or installation processes. Many users rush and skip these sections, thus exposing their systems to risk of various infections and compromising 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, carefully analyze each window of the download/installation dialogs and opt-out of all additionally-included programs. We also strongly recommend that you download your software from official sources only and, preferably, using a direct download links (most third party downloaders/installers are monetized using the "bundling" method). Intrusive ads often look legitimate, however, they redirect to dubious websites (gambling, pornography, etc.) If you experience these redirects, uninstall all suspicious programs/browser add-ons.
