Rootkits and viruses are both types of malware, but serve different purposes. A rootkit allows unauthorized access or hides other malware, while a virus is designed to achieve a specific goal. Rootkits are harder to detect and remove, often requiring a complete system wipe. It’s important to avoid all types of malware.
While a rootkit and a virus are both types of malicious software or malware, they are typically used to accomplish different purposes in a cyber attack. A rootkit is typically installed on a computer system to allow an unauthorized user to continue accessing that system or to hide the presence and activities of other types of malware. Viruses, on the other hand, are types of malware that are typically designed to attack a computer system in a very specific way and to achieve a certain goal.
Despite the fact that a rootkit and a virus are both forms of malware, they are used to perform different tasks. A rootkit is a malicious program that can be installed on a computer, at various levels within the operating system (OS), and thus mask other activities. This type of program typically infects the “root” operating system on a computer, hence the name, allowing other activity with that system which is then hidden by the rootkit. A rootkit is often used to create a backdoor entry point into a computer system to allow an unauthorized user to gain access to that system in the future, or it can be used to hide an infection with a virus or other type of malware.
The main difference between a rootkit and a virus is that a virus usually doesn’t work to hide the activities of other programs or to allow access to a system. A virus is typically developed to achieve a certain effect, often by launching an attack on a particular computer system. While a virus can lie fairly dormant on a computer system and remain undetected, until a particular event triggers the virus, it is usually created to launch a very specific attack on the system it infects.
There are also some important differences in how a rootkit and a virus can be removed from a computer system or an operating system. Viruses can often be found and removed by the user of an antivirus program, although very new viruses may escape detection for some time. A rootkit, however, can be very difficult to find, as it usually involves very elaborate security procedures and is nearly impossible to remove. It may be necessary to completely erase a computer’s hard drive and reinstall the operating system to get rid of a rootkit from a computer. Ultimately however, both a rootkit and a virus can be very destructive to a computer and every computer user should make efforts to avoid any type of malware.
