❓ Frequently Asked Questions
What is a cyber threat?
A cyber threat is any malicious action aimed at damaging, disrupting, or gaining unauthorized access to computer systems, networks, or data.
What is malware and what are common types?
Malware is software designed to harm or steal information. Common types include viruses (infect files and spread), worms (self-replicating across networks), trojans (disguise as legitimate software), ransomware (locks or encrypts data for a ransom), spyware (secretly collects data), and adware (displays unwanted ads).
How does ransomware differ from other malware?
Ransomware locks or encrypts your data and demands payment to restore access; other malware may steal data, monitor activity, or disrupt systems without a ransom demand.
How can I protect myself from cyber threats and malware?
Keep software and antivirus up to date, use strong passwords, back up data regularly, avoid suspicious links or downloads, enable security features, and practice safe browsing.
