What is a Virus?
A virus is a malicious software program that replicates itself by attaching its code to other programs or files. Unlike legitimate software, viruses cannot run independently. They rely on a host program or system to function and spread. Viruses can infect a wide range of devices, including computers, laptops, smartphones and even internet-of-things (IoT) devices.
Impact of viruses_
- Viruses can disrupt computer operations and cause various problems, including:
- Data loss or corruption: Viruses can damage or delete important files on your device, leading to data loss.
- System slowdown: Virus activity can consume system resources, causing performance issues and instability.
- Exposure to hackers: Some viruses can create backdoors or vulnerabilities that allow unauthorised access to your system by hackers.
- Spam and botnets: Infected devices can be used to send spam emails or become part of a botnet, a network of compromised devices controlled by attackers for malicious purposes.
