A question-answering system for searching exact answers in text documents provided in the electronic or digital form to questions formulated by user in the natural language is based on automatic semantic labeling of text documents and user questions. The system performs semantic labeling with the help of markers in terms of basic knowledge types, their components and attributes, in terms of question types from the predefined classifier for target words, and in terms of components of possible answers. A matching procedure makes use of mentioned types of semantic labels to determine exact answers to questions and present them to the user in the form of fragments of sentences or a newly synthesized phrase in the natural language. Users can independently add new types of questions to the system classifier and develop required linguistic patterns for the system linguistic knowledge base.

Scanning of the shadow copy instead of the hard disk of a computer (using an accessing interface instead of the file system interface or an API of the operating system) enables the scanning software to access any files that might have been locked by the malware on the hard disk and avoids root kits. Files cannot be locked because a disk parser is used instead of the operating system or normal file system interface. It is possible for malware to change or reinfect files during the scanning and cleaning process. Files on the hard disk in existence at the time a manual scan is begun are scanned and backed up to the cache if changed during scanning. Dropped malware is removed by reverting the hard disk to the shadow copy once scanning and cleaning has been performed. Even if a watchdog drops a file during the scanning and cleaning process (because it detects that other malware components are being affected) these dropped files will be removed.
