Understanding Computer Viruses
Computer viruses are malicious software programs designed to replicate and spread to other computers. Let's break down the statements to understand why option 'A' is correct.
Statement S1: A virus can replicate itself and spread to other computers.
- True: A key characteristic of a virus is its ability to replicate itself.
- Mechanism: Once a virus infects a host computer, it can attach itself to other programs or files, allowing it to spread to other systems, especially when shared through networks or removable storage devices.
Statement S2: A virus is always detectable by antivirus software.
- False: While antivirus software is designed to detect and remove viruses, it does not guarantee complete detection.
- Limitations: Some advanced viruses can evade detection through techniques like encryption, polymorphism, or simply by being new and not yet recognized by the antivirus database. Therefore, not all viruses are detectable at all times.
Conclusion
Given the analysis:
- Only S1 is correct because it accurately describes the self-replicating nature of viruses.
- S2 is incorrect due to the limitations of antivirus software in detecting every virus.
Thus, the correct answer is option 'A': Only S1 is correct. Understanding these aspects helps in better protection against computer viruses.
