Spyware and malware remain a serious problem and Microsoft developed an antispyware and antivirus, Windows Defender, to combat this threat. Any notifications of detecting, removing, or preventing these malicious programs should be investigated. In the event Windows Defender fails to operate normally, administrators should correct the issue immediately to prevent the possibility of infection or further infection. If a third-party antivirus and antispyware product is currently in use, the collection of these events is not necessary.
