The invention discloses an abnormal behavior detection method and device, computer equipment and a storage medium, relates to the technical field of information, and mainly aims to avoid deviation of user behavior data statistics so as to improve the detection precision of user abnormal behaviors. The method comprises the following steps: acquiring operation time corresponding to a plurality of operation behaviors of a to-be-detected user; determining a plurality of operation time intervals sorted according to a time sequence based on the operation time; calculating a period segmentation threshold value commonly corresponding to the plurality of operation time intervals, and determining a period time interval existing in the plurality of operation time intervals according to the period segmentation threshold value; dividing the plurality of operation time intervals into different time windows based on the weekly time intervals; and according to the operation frequency of the to-be-detected user in the differe
