Ohjelmavirhe, often referred to as a bug, is an error, flaw, or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways. These errors can range from minor inconveniences to critical failures that halt program execution or compromise system security.

The existence of program errors is a common phenomenon in software development. They can arise from a variety of sources, including mistakes in the source code logic, incorrect assumptions made by the programmer, issues with the hardware environment, or unexpected interactions between different software components. Poorly defined requirements or misunderstandings of user needs can also contribute to the development of buggy software.

Identifying and rectifying program errors is a crucial part of the software development lifecycle, a process known as debugging. This typically involves systematic testing, code analysis, and the application of various debugging tools and techniques. Programmers use debuggers to step through code execution, inspect variable values, and pinpoint the exact location of the error.

The impact of program errors can vary significantly. Some bugs may only affect a small subset of users or specific functionalities, while others can lead to widespread system outages or data corruption. In critical systems, such as those used in aviation, medical devices, or financial institutions, even minor bugs can have severe consequences. The ongoing effort to minimize and eliminate program errors is central to ensuring the reliability, security, and usability of software.
