Hidden Bee virus removal guide
What is Hidden Bee?
Hidden Bee (also known as Hidden Mellifera) is a trojan-type infection designed to mine cryptocurrency. Therefore, it diminishes system performance. This malware infiltrates computers without users' consent and research shows that cyber criminals proliferate Hidden Bee using the Popcash advertising network and Underminer Exploit Kit (EK).
Hidden Bee works as a 'bootkit' - it runs itself on each system startup. Furthermore, it disguises itself well, and can go unnoticed unless users study system resource usage. Therefore, the only real indication of the presence of Hidden Bee is significantly reduced computer performance. Hidden Bee is a malicious cryptominer, which hijacks systems and uses resources to mine cryptocurrencies without users' consent. Be aware that very powerful hardware is necessary to efficiently mine cryptocurrency, since electricity bills and other expenses are significant. Therefore, the entire process can be costly. To avoid time and money building mining rigs, cyber criminals develop malicious miners such as Hidden Bee and proliferate them. An average home PC is not a good choice to mine cryptocurrency, since the cost of electricity is higher than any revenue generated, however, infecting thousands of machines and not having to pay is another strategy that can work for criminals. Therefore, proliferating malicious miners is becoming increasingly popular. Hidden Bee employs mainly CPU resources, however, there also are traces of CUDA platform/API usage. Thus, it might also employ Nvidia graphics cards. Cryptocurrency mining is essentially a process by which computers solve various mathematical equations. The same equation is solved by multiple computers at once (all data is transferred through the Internet) and the more problems solved, the more revenue the owner generates, and the more cryptocurrency is mined. The process can take up to 100% of system resources and the system can become unstable (it is likely to crash) and virtually unusable (it barely responds). Furthermore, fully-loaded hardware components generate excessive heat and, within certain circumstances (high room temperatures, bad cooling systems, etc.), they might overheat and be permanently damaged. Furthermore, all revenue goes to cyber criminals, whilst victims take all risks with no benefits in return. As mentioned above, Hidden Bee is distributed using an exploit kit. In fact, cryptominers are often distributed using trojans, which cause "chain infections". Therefore, if you have noticed a significant increase in resource usage (the components often work at their maximum, even when no software is running), we strongly advise you to scan the system with a reputable anti-virus suite and eliminate all detected threats.

To eliminate Hidden Bee virus our malware researchers recommend scanning your computer with Spyhunter.
There are dozens of malicious trojans that share similarities with Hidden Bee. The list of examples includes Plurox, Megumin, Tofsee, and many others. These infections have some differences (they mine different cryptocurrencies, use different computer components [GPU/CPU], and so on), however, they cause identical issues - they reduce computer performance and can damage hardware. Therefore, eliminating malicious cryptominers is paramount.
How did Hidden Bee infiltrate my computer?
Hidden Bee is promoted using the Popcash advertising network and Underminer EK. The advertising network is used to redirect users to malicious websites that exploit Internet Explorer and Adobe Flash Player vulnerabilities to infiltrate UnderMiner EK into the system. This Exploit Kit then injects the Hidden Bee cryptominer into the system by communicating with a remote server and downloading/installing Hidden Bee. In addition, this miner is typically injected into a number of system files. Cryptominers are often distributed using spam email campaigns, third party software download sources, and fake software updaters and 'cracks'. Criminals employ spam campaigns to send hundreds of thousands of deceptive emails containing malicious attachments and messages encouraging recipients to open them. Unofficial software download sources present malicious executables as legitimate software, thereby tricking users into downloading and installing malware rather than updates. Fake updaters and cracks infect computers rather than updating software or activating it free of charge. In summary, the main reasons for computer infections are poor knowledge of these threats and careless behavior.
How to avoid installation of malware?
Be very cautious when browsing the Internet and downloading/installing/updating software. Download apps from official sources only, using direct download links. Keep installed applications and operating systems up-to-date, however, use only implemented functions or tools provided by the official developer. Using third party downloaders/installers/updaters is risky, since these tools often include rogue apps. Cracking installed applications is illegal (software piracy is a cyber crime) and the risk of infections is extremely high, since most cracking tools are fake. Therefore, never attempt to activate software using illegal/third party tools. Handle all email attachments with care. Files/links received from unrecognizable/suspicious addresses should never be opened. The same applies to attachments that are irrelevant or do not concern you. Finally, have a reputable anti-virus/anti-spyware suite installed and enabled, since this will remove infections before they can harm the system. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck the "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.
You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.
Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.
To be sure your computer is free of malware infections we recommend scanning it with Spyhunter for Windows.
