Types of Destructive Software
- Viruses
- File viruses
- System sector viruses
- Macro viruses
- Worms
- Trojans
- Logic bombs
- Spyware
Damages Caused by Viruses
- Viruses can damage programs, delete files, and reformat or erase hard drives, resulting in reduced performance or crashing systems entirely.
- Hackers can use viruses to access personal information, steal, or destroy data.
Characteristics of Malware
- Malware is any program or file intentionally harmful to a computer, network, or server.
- Types of malware include computer viruses, worms, Trojan horses, ransomware, and spyware.
How Viruses Work
- Viruses execute when an infected program is executed, infecting other programs with copies of itself or damaging programs and data.
- Trojans contain malicious code that, when triggered, cause loss or theft of data.
- The main purpose of a worm is to self-replicate and propagate across the network.
Virus Protection
- Virus protection software is designed to prevent viruses, worms, and Trojan horses from getting onto a computer and remove malicious software code that has already infected a computer.
- Most virus protection utilities now bundle anti-spyware and anti-malware capabilities with anti-virus protection.
Importance of Antivirus Software
- Data breaches have increased by 68% in 2021, putting personal information such as Social Security numbers, birth dates, and bank account information at risk.
