Ransomware is a new form of malware that interferes with access to user files and data by encrypting it. The FBI sent an urgent ‘Flash’ message to businesses and organizations warning of new forms of malware. Victims get attacked with ransomware when they unknowingly click on a malicious link or open an infected file sent to them as an email attachment. Filtering out infected emails before they reach the users inbox and blocking malicious links are the most efficient methods of preventing malware infections.”]
