MS-DOS was first released in 1981 and updated until 1994 when it was replaced by Windows 95. All versions of Windows still contain some elements of DOS.
The basic structure of DOS commands uses the format "Command Source Destination /Switch". Commands include COPY, XCOPY, DIR, DEL, EDIT, MOVE, REN, MD, DELTREE, and TREE.
The DOS prompt displays the current directory. File names cannot be longer than 8 characters and extensions no more than 3 characters. Basic commands like CD, CD.., COPY, DIR, DEL allow navigating and managing files and folders.
A computer virus is a type of malicious software or malware that can replicate itself and spread by inserting copies of its code into other computer programs or files. When executed, the virus code can damage programs, delete files, or disrupt the operation of the computer. Viruses spread similar to biological viruses by making copies of themselves that get transferred to other computers or storage devices. Common symptoms of a virus infection include programs running slowly, unexpected computer behavior, and files being deleted or corrupted.
This document discusses computer viruses and how to protect against them. It defines a computer virus as a program that replicates by copying itself to other programs or devices. It then lists common types of viruses like worms, ransomware, spyware, and botnets. To protect devices, it recommends not connecting to unknown USB drives or opening email attachments, and using antivirus software and online scanning services. It provides examples of an Eicar test file and the VirusTotal scanning site to demonstrate online scanning.

MS-DOS was an early operating system owned by Microsoft that was based on 86-DOS, which was owned by Seattle Computer Products. Microsoft needed an operating system for Intel's 8086 processor and licensed 86-DOS from Seattle Computer Products. MS-DOS 1.0 was then released with the IBM PC in 1982. There were internal commands that were loaded with the operating system and external commands that had to be loaded from disk before use. MS-DOS featured text files, batch files, and supported file names with extensions organized in directories with relative and absolute paths.
