Abstract
Anomalous loading of a dynamic-link library (DLL) is detected on a desktop computer. When the file of the DLL is not a known normal file, the locality sensitive (LSH) values of files of known versions of a known normal DLL that corresponds to the DLL are obtained from an LSH repository and compared to the LSH value of the file of the DLL. The smallest distance between the LSH value of the file of the DLL and each of the LSH values from the repository is selected for comparison to a risk threshold. The Loading of the DLL is detected to be an anomaly when the smallest distance is not less than the risk threshold.
