Which of the following is NOT typically a carrier of malware?

The correct choice indicates that dual in-line memory modules (DIMMs) are not typically carriers of malware. This is because DIMMs are hardware components that serve as a type of computer memory, primarily used to store data temporarily while a computer is running. They do not contain executable files or software that could be manipulated to carry malware. Instead, they simply provide the necessary memory for the system to function, making them an unlikely medium for malware transmission.

In contrast, email attachments, files downloaded from the internet, and freeware or shareware files are all potential carriers of malware because they can include executable code or scripts that may contain malicious software. Email attachments could easily disguise harmful files, while files downloaded from the internet can be infected deliberately by malicious actors. Freeware and shareware, although often legitimate, can sometimes be bundled with unwanted software or malware during the installation process. Thus, the role of DIMMs as a hardware component without the capacity to store or execute files categorizes them distinctly from the other options listed.
