Understanding the Threat Landscape
The digital world presents a multitude of threats. Malware, viruses, spyware, and ransomware are just a few examples of malicious software designed to compromise your computer's security and steal your sensitive information.
Common Types of Malware
- Viruses: These programs self-replicate and spread to other files, potentially causing significant damage.
- Worms: Similar to viruses, worms spread independently across networks, often disrupting network services.
- Trojan Horses: Disguised as legitimate software, Trojans can grant unauthorized access to your system.
- Spyware: This type of malware secretly monitors your online activity, collecting personal information without your knowledge.
- Ransomware: This malicious software encrypts your data and demands a ransom for its release.
How Malware Infects Your System
Malware can enter your system through various means, including downloading infected files, clicking on malicious links, or visiting compromised websites. Understanding these entry points is essential for prevention.
Choosing the Right Antivirus Software
Selecting the appropriate antivirus software is crucial for effective protection. Consider factors like performance impact, detection rates, and user interface when making your decision.
Key Features to Look For
