When the program runs, the written virus program is executed first, causing infection and damage. By contrast, a computer worm does not need a host program, as it is an independent program or code chunk. Therefore, it is not restricted by the host program, but can run independently and actively carry out attacks. Virus writers use social engineering deceptions and exploit detailed knowledge of security vulnerabilities to initially infect systems and to spread the virus. Viruses use complex anti-detection/stealth strategies to evade antivirus software. Motives for creating viruses can include seeking profit (e.g., with ransomware), desire to send a political message, personal amusement, to demonstrate that a vulnerability exists in software, for sabotage and denial of service, or simply because they wish to explore cybersecurity issues, artificial life and evolutionary algorithms.

On most Windows systems, if the user extracts the whole zip file (including the "libs" folder) to a new folder or their desktop, it should just run. The download is a zip file containing both the 32-bit and 64-bit executable and supporting DLLs, and the English user manual. It includes several bug fixes and now enables the last selected hash value to be saved on exit by popular demand. This is version 3.3.3 of QuickHash-GUI for Windows.
