PROTECTION SYSTEM FOR COMPUTERS
专利汇可以提供PROTECTION SYSTEM FOR COMPUTERS专利检索，专利查询，专利分析的服务。并且A system and method for protecting computer systems from computer viruses. The system (301) generally consists of a protection device (17) interposed between the computer and the hard disk drive (15, 307). The protection device (17) is connected between the disk controller (13, 303) and the disk drive (15, 307) to intercept relevant control signals issued by the controller (13, 303) to the disk drive (15, 307) and selectively override the signals in accordance with a prescribed protection scheme to protect unauthorised reading or writing of predefined protected areas of the disk drive (15, 307). The protection device (17) can also be connected to the main communication bus (305) of the computer to enable the CPU of the computer to drive the initialisation means to configure the protection scheme for the disk. Alternatively, the initialisation means may be implemented in software stored within a protected area of the disk, which software is run early in the power up sequence of the computer system performed from a cold boot. In either case, the initialisation means is operated early in the power up sequence before the disk operating system stored on the disk (15, 307) is loaded into the main memory of the computer to effect normal operation of the computer system.，下面是PROTECTION SYSTEM FOR COMPUTERS专利的具体信息内容。
