A Host Intrusion Prevention System or HIPS is a security program that will protect individual computers (aka 'hosts') against viruses and other internet malware.
Other types would include Network Intrusion Prevention Systems which can protect against a network attack but not other attacks that would include, for example, an infected program in a portable USB drive/pen drive and Host Intrusion Detection Systems which will detect but cannot stop an attack.
