Great Discover virus is a type of malware program that is regarded as a Trojan Horse. It is dangerous in some cases and causes the same result as other malware programs, such as system lagging or resource waste. To remove this virus and figure it out, you can refer to this article on MiniTool Website.

What Is a Great Discover Virus?

First of all, what is a Great Discover virus? It is easy to classify the Great Discover virus as a malware program – Trojan Horse – but most people wonder about its specific uses.

When infected by a Great Discover virus, it can use your system resources to mine BitCoin, Monero, Dask, or other cryptocurrencies for its creators, slowing down your computer, and even causing a system crash or other severe results.

Apart from a crypto-mining threat, it also may be far worse than the typical adware. It can deliver unwanted advertisements to the victim system, diminishing the users’ browsing experience. Besides, it can initiate its processes in the background and start to siphon off the system's hardware resources.

When the Great Discover virus starts working, the GPU, CPU, and RAM will be affected and all hijacked resources will be used to generate coins for a specific cryptocurrency, depending on the preferences of its operators.

The clever thing about the virus is that only on a system with a powerful enough GPU and CPU and enough memory, Great Discover activity may go unnoticed. To help it maintain its cover over a longer period of time, the threat can also be activated only when the computer is not heavily loaded.

However, on older devices, users may notice various applications running abnormally, lagging, becoming unstable, or even crashing, and the operating system itself may become slower and often freeze.

So how does the Great Discover virus infect the computer?

Just like other malware, the Great Discover malware program sneaks into your computer with camouflage through dubious software installers. Some users seek a cracked version of a legitimate software product for free to avoid any payments, which provides a channel to those malware programs installed.

Installers obtained from these untrustworthy sources offer not the desired product, but various adware, browser hijackers, PUP (potentially unwanted programs), or, in this case, crypto mining threats.

To avoid such a thing happening, the first thing you need to do is to download it via official websites. Besides, you also need to read the small text carefully and check the advanced settings of the installer you are running on your computer.

Once an unwanted program is installed on the computer, it drops several malicious files on the Windows system and the Great Discover virus can try to disable the Windows firewall so that it can succeed in manipulating your computer and exploiting your resources.

Great Discover can conceal its presence but there are some identification marks you can notice.

Since the Great Discover Trojan will waste many resources, you can open the Performance tab of Task Manager and if there are most of your computer's RAM and CPU being used up even without any resource-consuming programs currently running in the system, then your computer may have been infected with the Great Discover virus.

Sometimes, the Great Discover virus will be inserted into your computer as a rogue program. It is easy to identify with its name and you can directly remove it through some steps we will introduce in the next part.

However, if you can’t certain which one is the Great Discover process, it is preferable to use a reputable anti-malware solution to do a thorough scan and then remove the detected items.
