The book is about the architecture, design, and evolution of antivirus engines, explaining how they detect, analyze, and defend against malware using various technical methods and innovations.

This project provides a minimal Python implementation of a Hash Table using separate chaining for collision handling. It supports insertion and search of key value pairs, with a compact design that…

A repository for resources and updates related to the Algorithms (MDPI) special issue. Focused on secure algorithmic solutions for cyber defense, including encryption, authentication, anomaly detec…

This example scans a range of values and then it builds a string-based distribution. The distribution function iterates through inputs, applies compute(x) using the main arithmetic expression (x+x/…

This example generates a vertical bar chart in Python using ASCII characters. Random values are stored in an array and visualized with block symbols, while an ASCII axis and labels enhance readabil…

This example implements a general logic gate in Python by merging multiple logical operations into a single function. Two binary 3×3 matrices are processed element-wise with an operation code to pr…

This example detects and labels islands in a 2D grid, calculating their percentage coverage. It demonstrates recursion, array traversal, and formatted output, with applications ranging from image a…

This example decomposes a matrix into multiple matrices based on its unique values. It demonstrates array traversal, and decomposition, showing how complex structures can be broken into simpler com…

This example demonstrates a low-level native sort with duplicate elimination. It builds array (a) from values in (b), then reconstructs (b) with unique sorted values. Runtime is n+m, where m is the…

This example computes three core statistics from an array (a), namely the average (AV), standard deviation (SD), and coefficient of variation (CV). Results are derived step by step and returned in …

This example calculates the Pearson correlation coefficient (r), by measuring the linear relationship between two arrays. The use of means and then the accumulators, shows how covariance and varian…

This example implements a Bloom filter in Python, a probabilistic data structure for fast membership testing. Items are added using multiple hash functions that set bits in a fixed-size array. Memb…

This example presents a file alignment utility in Python with a simple Tkinter interface. It extracts the first bytes of each file in a selected folder and prints them as aligned hexadecimal string…

This example implements an optimized antivirus scanner in Python using the Aho-Corasick automaton. It combines signature matching with a Tkinter interface, extension-based filtering, and progress r…

This example shows the Aho-Corasick algorithm for multi-pattern search in Python. It builds a trie with failure links to scan text efficiently in linear time, detecting all occurrences of given pat…

This example presents a native antivirus scanner in Python with a self-contained Aho-Corasick implementation. It removes external dependencies, adds visual position markers for detected signatures,…

This repository includes the ".bas" files for Markov Chains that accompany the book entitled: Markov Chains: From Theory to Implementation and Experimentation. These ".bas" implementations can be u…

These Markov Chains .BAS modules accompany the book entitled: Markov Chains: From Theory to Implementation and Experimentation, and they are compatible with Visual Basic for Applications (VBA) and …
