Learn about different types of malware and how to protect against them.

What is Malware?

Malware, short for malicious software, is any software intentionally designed to cause damage to a computer, server, or network.

Types of Malware

1. Viruses

A virus attaches itself to a legitimate program or file and spreads from one computer to another, leaving infections as it travels.

2. Worms

Worms are standalone software that replicate themselves to spread to other computers, often exploiting vulnerabilities in network security.

3. Trojans

Trojans disguise themselves as legitimate software but carry malicious code. They can create backdoors, allowing unauthorized access to the system.

Signs of Malware Infection

2. Regular Scans: Perform regular system scans to detect and remove malware.
3. Update Software: Keep your operating system and applications up to date.
4. Avoid Suspicious Links: Do not click on unknown links or download attachments from untrusted sources.
5. Use a Firewall: Enable a firewall to block unauthorized access.
