 DIFFERENCE BETWEEN ROOTKITS & VIRUS 

🔻 ROOTKITS

🌀 They are a set of tools that enable the intruder to maintain his stealth after gaining access to the system.In other words,the intruder uses rootkits in order to maintain access to the remote system without the owner’s knowledge.

Rootkits for Windows are typically used to hide malicious software from, for example, an antivirus program. It is used for malicious purposes by viruses, worms, backdoors, and spyware. A virus combined with a rootkit produces what as known as full stealth viruses. Rootkits are more common in the spyware field, and they are now also becoming more commonly used by virus authors as well.

There are basically three different types of Rootkit. The first type, the “Kernel Rootkits” usually add their own code to parts of the operating system core, whereas the second kind, the “User-mode Rootkits” are specially targeted to Windows to startup up normally during the system start-up, or injected into the system by a so-called “Dropper”. The third type is MBR rootkits or Botkits

🔻 VIRUS

🌀 Malicious software that causes damage to a computer system.The damage can range from repeatedly displaying a pop-message to crashing the system and loss of important databas duplicates itself within a computer system,potentially attaching itself to every software application.In more technical terms, a computer virus is a type of malicious code or program written to alter the way a computer operates and is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code. In the process, a virus has the potential to cause unexpected or damaging effects, such as harming the system software by corrupting or destroying data.
