Malware is software designed to steal, spy, disrupt, extort, or give attackers control. Common forms include ransomware, trojans, spyware, downloaders, and credential stealers.

What business leaders should understand
Modern attacks often combine malware with stolen accounts and legitimate administration tools. Prevention therefore requires more than traditional signature-based antivirus.
The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.
