Malware and ransomware basics
An educational, non-alarmist look at common threat categories and how prevention-based tools generally aim to address them.
Malware
Software designed to damage systems, steal information, or gain unauthorized access.
Ransomware
Malware that encrypts files and demands payment for their release; prevention-based approaches aim to stop it before it runs.
Phishing
Deceptive messages that try to trick recipients into revealing information or installing malware.
Zero-Day Threats
Newly discovered attack methods that haven't yet been catalogued by traditional malware databases.
Fileless Attacks
Malicious activity carried out through scripts or system processes rather than a traditional downloaded file.
Software Vulnerabilities
Unpatched software can create openings that attackers exploit; regular updates help close these gaps.
General security habits
Keep software updated
Applying updates promptly helps close known security gaps.
Keep independent backup copies
Backups stored separately from your main system can help you recover without paying a ransom.
Be cautious with links and attachments
Unexpected messages asking you to click links or open attachments deserve extra scrutiny.
Use layered protection
Combining prevention-based tools, careful habits, and backups generally offers stronger protection than any single measure alone.
