Malicious programs, also known as malware, are software programs designed to disrupt, damage, or gain unauthorized access to a computer system or network. These programs can take many forms, including viruses, worms, trojans, ransomware, spyware, and adware.
Five common effects of malware include:
1. Data theft: Malware can be used to steal sensitive information such as personal and financial data, login credentials, and intellectual property. This stolen data can then be used for identity theft, fraud, or other malicious purposes.
2. System damage: Malware can corrupt or delete files, damage hardware components, and disrupt the normal functioning of a computer system. This can lead to system crashes, data loss, and the need for costly repairs or replacements.
3. Network disruption: Malware can spread rapidly across a network, infecting multiple devices and causing network congestion or downtime. This can disrupt business operations, communication, and access to critical resources.
4. Financial loss: Malware can be used to carry out financial fraud, such as unauthorized transactions, ransom demands, or extortion. Businesses and individuals can suffer significant financial losses as a result of malware attacks.
5. Privacy invasion: Malware can monitor and record a user's online activities, including browsing history, keystrokes, and webcam footage. This invasion of privacy can lead to identity theft, blackmail, or other forms of exploitation.
