What is resident virus virus?
A type of malware that hides and stores itself within the computer’s memory. Depending on the virus’ programming, it can then infect any file run by the computer. This type of virus even attach itself to anti-virus applications, thereby allowing it to infect any file scanned by the program.
What is resident and non resident virus?

What is the difference between resident and non resident memory?
Non-resident computer viruses are executable. In comparison, resident computer viruses don’t require manual execution. A resident computer virus will stay within your computer’s RAM where it’s able to perform its malicious activities at any time.
How do resident viruses spread?

Once initialized, the virus could infect the drive or diskette and spread itself to any other computer that uses that drive or diskette.
What is the difference between resident and non-resident memory?
What is non-resident memory?
When nonresident memory is accessed, data is copied to that memory from a disk or other storage. It therefore requires complicated processing such as disk access by a device driver. Accordingly, when nonresident memory is accessed, the device driver, etc., must be in operational state.
What is rootkit virus?
A rootkit allows someone to maintain command and control over a computer without the computer user/owner knowing about it. Once a rootkit has been installed, the controller of the rootkit has the ability to remotely execute files and change system configurations on the host machine.
What is the advantages of memory-resident malware?
