Malware, short for malicious software, is any program or file intentionally designed to harm a computer, server, client, or network. It is a broad term encompassing various types of harmful software that can steal, encrypt, or delete your data, hijack core computing functions, and spy on your activity without your knowledge.

Common types of malware include:

• Viruses: Attach to clean files and spread, damaging system files.
• Worms: Replicate themselves to spread to other computers, often via a network.
• Trojan Horses: Disguised as legitimate software to trick users into installing them.
• Ransomware: Locks or encrypts your files, demanding payment for their release.
• Spyware: Secretly gathers your personal information.

Malware typically infects devices through:

• Email attachments or links.
• Downloading software from untrustworthy sources.
• Visiting compromised websites (drive-by downloads).
• Connecting infected external drives.

To protect your hosting account and website, it is crucial to:

• Keep all software, including your CMS (like WordPress), updated.
• Use strong, unique passwords and enable two-factor authentication.
• Install a reputable security plugin or solution.
• Regularly back up your website data to a secure, off-site location.

Understanding malware is the first step in building a strong defense for your online presence.
