The Great Discover Virus

The Great Discover Virus is a malware type categorized as a Trojan Horse that exploits the system resources and uses them for cryptocurrency generation, which severely slows down the computer. Any amount of cryptocurrency generated by the Great Discover Virus goes directly to its creators.

The Great Discover virus likely has gained some pretty extensive privileges in the machine

If you have this malware program on your computer, the main symptom you may have noticed is a significant decrease in the speed and responsiveness of your system. If you open the Task Manager’s Performance tab and there you see that most of your computer’s RAM and CPU is being used up even when there aren’t any resource-intensive programs currently running in the system, this could be a strong indication that you might be dealing with the Great Discover virus.

The good news is that it is likely that this virus will not try to damage the computer or the data you store on it. The goal of the Great Discover is to remain on your PC for as long as possible in order to keep leeching off of your system resources and generating cryptocurrency for its creators. Still, even though there are currently no reports of this Trojan attempting to damage any systems that it has infected, it is most definitely not safe to keep it on the computer. Since this virus likely has gained some pretty extensive privileges in the machine, it is not beyond the realm of possibility that the hackers who control it may choose to exploit those privileges and harm your computer, steal your data, or infect the PC with more malware, including sneaky Spyware threats, file-encrypting Ransomware viruses, rogue browser-targeting Adware and Hijacker extensions, Rootkits, other Trojans, and more.

What is the Great Discover?

The Great Discover is a malware program that leeches system resources off of the infected  computer to mine BitCoin, Monero, Dask, or other cryptocurrencies for its creators. If the Great Discover virus has infected your PC, there will likely be slow-downs and other performance issues.

It’s possible that some versions of this malware only mine cryptocurrency when the computer is idle so that the user won’t notice the presence of the virus. However, in other cases, the mining activities may be running at all times which could make the computer very slow and sluggish and prevent you from using it normally. Not only could this severely hinder your working process on the computer, but it could also put a massive strain on the machine’s hardware which, in turn, can contribute to an accelerated wearing-out process of the whole PC.


Like most threats of the Trojan Horse family, the Great Discover virus primarily relies on the use of disguise to make its way into its victim’s computers. Whether through a spam email message with a misleading download link, a fake update request for some app that you may or may not have, or through being bundled to another, more presentable piece of software, the distribution method used to get this Trojan added to your system would always be aimed at tricking you and making you think you are not downloading a virus but rather something useful or at least something that’s not malicious. This is why, in order to prevent landing this, or another similar malware, in the future, it is strongly recommended to, firstly, be very selective about the sources you use to download new software and, secondly, to always read the small text and check the Advanced setup options of the installers you are running in the computer because this is can help you notice if anything potentially unwanted has been added to a program that may otherwise look legitimate.

    In some cases, The Great Discover Virus may incorporate malicious startup entries in the Startup section of your computer in order to launch its harmful processes as soon as the computer starts. Therefore, you need to check for such entries and remove them.

    This can be done by typing msconfig in the windows search field and hitting enter to open the System Configuration window: 


    Next, click on the Startup tab to search the startup entries for questionable ones. If you find any, uncheck their checkmark. Any entries with “Unknown” Manufacturer should best be researched online to find out if they are legitimate or not before you decide whether to uncheck them.

    Attention! Trojans may act as a backdoor for other malware. Therefore, if you have been infected with The Great Discover Virus, you should check if a bigger threat (like spyware or ransomware) has compromised your PC without your knowledge and has hacked your system. This can be done in the following way:

    • Press the Start and R keyboard keys together.
    • A dialog box named Run will appear on the screen.
    • Copy the line below in the Run box :

    notepad %windir%/system32/Drivers/etc/hosts

    • Press Enter to execute the command.
    • This will open a text file named Hosts.
    • Scroll the text in the Hosts file and find where it is written Localhost.
    • Then, carefully look at the example image below. 

    hosts_opt (1)

    • If your system is not compromised, you shouldn’t see anything disturbing.
    • If you are hacked, however, you may see dozens of strange IPs under Localhost just as explained in the image. In this case, we invite you to leave us a comment below this guide, so we can provide you with instructions on what to do in this scenario.


    A lot of Trojans can make changes in the Registry of the infected computer and add malicious entries that affect the system’s stability. To remove these entries you need to start the Registry Editor app on your computer by typing Regedit in the windows search field and pressing the Enter key

    Next, by pressing CTRL and F keys together, open the Find function and type the name of the Trojan in the Find dialog box. Press Find Next to search the Registry and delete all entries that are found with that name.

    Finally, go manually to each of the listed directories below and uninstall/delete them:

    • HKEY_CURRENT_USER->Software->Random Directory. 
    • HKEY_CURRENT_USER->Software->Microsoft->Windows->CurrentVersion->Run->Random
    • HKEY_CURRENT_USER->Software->Microsoft->Internet Explorer->Main->Random

    If The Great Discover Virus still keeps messing with your system after you complete all the steps above, it is best to scan the computer with the anti-virus program listed on this page to search for hidden elements that help the Trojan’s persistence. Also, use the online virus scanner to scan any questionable files.
