What is Malware?
Malware is malicious software designed to harm a device, steal information, or disrupt normal computer use. It can spread through emails, downloads, websites, or infected files.
In more detail
Malware is short for malicious software. It includes harmful programs such as viruses, worms, ransomware, spyware, and trojans. Once installed, malware may damage files, slow down your device, spy on your activity, or lock you out of your own data.
It matters because malware can affect anyone who uses a phone, computer, or tablet. A simple click on a bad link, a fake attachment, or a shady download can be enough to let it in.
In everyday use, malware can cause annoying pop-ups, strange behavior, stolen passwords, or even financial loss. Good habits like keeping software updated, avoiding suspicious links, and using security tools can help reduce the risk.
Examples
- A fake email attachment that installs ransomware
- A spyware app that secretly tracks browsing activity
- A trojan download that looks like a free game or tool
