SYSTEM FOR PREVENTING ACTIVATION OF COMPUTER VIRUSES AND OTHER TYPES OF MALICIOUS SOFTWARE PROGRAMS ENTERED INTO COMPUTER HARD DISKS

摘要

Invention herewith described refers to the system for preventing activation of computer viruses and other types of malicious codes entered into computer hard disks is basically carried out during entering, or installation of a software applications when it is necessary to carry out encryption of the data files meaning that the user itself is required to enter the unique cipher key for each hard disk. When reading executable data files from the disk, decryption of data files is done automatically in the electronic assemblies of hard disk itself or the accompanying circuits and before forwarding these data files into the computer memory. Thus in the case of a regular application programme that the user wants to install, these data files go through a regular encryption procedure and during their decryption the original non-crypted data will be obtained. In the cases when the virus by itself enters into the hard disk, without encryption process when the user enters the cipher key, it will be destroyed during the reading process in the decryption procedure and hence its activation and execution in the hard disk will be prevented.
