Malware, in simple terms, refers to malicious software that is designed to harm or exploit your computer or mobile device. It can enter your device through various means, such as clicking on a malicious link, downloading infected files, or visiting compromised websites.
Once malware is on your device, it can perform harmful activities without your consent or knowledge. This can include stealing your personal information, such as passwords or credit card details, spying on your activities, or causing your device to malfunction. Malware can also spread to other devices on a network, causing further damage.
It is important to protect your devices from malware by using antivirus software, keeping your operating system and applications up to date, and being cautious when clicking on links or downloading files from unknown sources.
