Resident Virus Examples
- CMJ Virus: One of the earlier examples of a resident virus, it infects .exe files and can stay memory-resident, executing its payload without the need to run the infected files again.
- Randex: This virus spreads through network shares and can receive commands from an attacker via a network. It resides in memory, making it active even if the infected file isn’t being executed.
- Mebroot: Mebroot infects the Master Boot Record (MBR), ensuring it is loaded into memory before the operating system. From there, it can carry out its malicious activities carefully.
- Virut: It is known for infecting executable files and HTML files, Virut creates a backdoor that allows remote access to the infected computer. Being a memory resident allows it to continuously spread and opens the door for further infections.
- Conficker: Conficker can reside in memory and infect devices across networks. It exploits vulnerabilities in Windows OS to spread and can disable security services, making it harder to remove.
What is a Resident Virus? Examples and Protection
Resident Virus is a type of malware that hides and saves itself in the computer’s memory. Depending on how the virus is programmed, it can infect any file run by the computer. This type of virus can even attach itself to anti-virus software, allowing it to infect any file verified by the program.
