Antimalware is a type of software program designed to prevent, detect, and remove malicious software (malware) on an electronic device.  Although it is similar to antivirus, it has important differences from antivirus. Antimalware has more advanced features such as behavior monitoring that scans for suspicious behavior or files on the device. It can prevent malware from installing.  It addresses spyware, spam, and other threat issues that antivirus usually does not.
