    B-tree with fixed node size and no minimum degree In anti-virus and anti-spyware applications, due to multiplicative increase in processing times with increasing complexity of detection logic and fast growing number of signatures, there is a necessity for data structures for quick retrieval and efficient storage of large collection of signatures. This paper presents a variant of B-tree data structure, where the minimum degree constraint is relaxed while maintaining the order of worst case performance bounds for primitive search, insert and delete operations of the B-tree. It presents a detailed case study of the impact of key(signature) size on storage utilization, given fixed sized nodes and also derives a maximum optimal key size with respect to node size. This variant of B-tree is found to be specifically very useful for storage of large number of keys where size of keys exhibit a wide variation and node size remains fixed
