How to remove Grand Explorer from computers
Written by Tomas Meskauskas on (updated)
What kind of program is Grand Explorer?
The Grand Explorer app is marketed as a tool that enables users to securely contribute their computer's idle time to perform complex calculations and problem-solving tasks. According to its description, the app operates exclusively during periods of computer inactivity and has no impact on performance when users are actively using their computers.
In essence, Grand Explorer operates as a cryptocurrency miner. Moreover, it is distributed alongside other unwanted apps.
Grand Explorer in detail
As a cryptocurrency miner, Grand Explorer utilizes computer resources to perform complex mathematical calculations, a process known as mining, to validate transactions on a blockchain network and generate new units of cryptocurrency as a reward.
The app might strain system resources excessively, particularly during active computer usage. This could result in a notable decline in overall system performance, causing delays and inefficiencies in tasks unrelated to the application. Users may find their computers responding more slowly, affecting their experience and productivity.
Also, the operation of Grand Explorer might lead to increased power consumption, which can result in higher energy bills. There is also a risk that Grand Explorer could conflict with other software or processes running on a user's computer.
It is known that Grand Explorer is distributed with other shady apps. This raises concerns about potential security risks for users. These bundled apps could include malicious software, adware, browser hijackers, or other unwanted programs that may compromise the user's privacy and system integrity.
Shady apps often engage in practices such as intrusive advertising, data tracking, or even more severe actions like installing malware. Therefore, it is highly advisable to uninstall Grand Explorer from compromised computers and thoroughly examine the system for any additional components that may have been installed alongside it.
