Virus

 Here are broad definitions of each term in the context of cybersecurity and digital threats:

1. **Spyware**: Software designed to secretly monitor and collect information about a user’s activities on their device, including browsing habits, keystrokes, and personal data, often without their consent. This data may be sent to third parties for various purposes, such as advertising or identity theft.

2. **Spamming**: The act of sending unsolicited messages, typically in bulk, to a large number of users. Spam is often sent via email but can also appear in text messages, social media, and comments. It may promote products, contain phishing links, or attempt to scam recipients.

3. **Ransomware**: Malicious software that encrypts or locks a user’s data, preventing access until a ransom is paid, usually in cryptocurrency. Ransomware attacks often target individuals, businesses, or institutions, and attackers threaten to delete or leak data if the ransom is not met.

4. **Virus**: A type of malicious code or program that attaches itself to legitimate software and spreads by infecting other programs or files. Once active, viruses can corrupt, steal, or delete data, and often slow down or disable devices.

5. **Trojans**: Malicious programs that disguise themselves as legitimate software. Once installed, they can create backdoors, allowing attackers to access the user’s system, steal data, install more malware, or take control of the device.
