How to use and maintain the hard disk and the measures of virus prevention

It is an effective way to prevent virus and maintain computer security to strengthen safety consciousness and enhance the management of computer. Many effective measures are listed below:

Establish sound rules and regulations and strictly manage the use of computer systems.

To strengthen the education of computer virus and its harmfulness to the staff. thereby consciously enhance the awareness of anti-virus.

The computer in the important department should be specially dedicated. Don't use a floppy disk or a U disk that was used on another machine. Before installing the software, you should check to make sure there is no virus. Seal all floppy disk and U disk write protection. When you need to write a person, temporarily unsealed, finish the post.

Maintain regular file and data backup. Make as many copies as possible, use them alternately, update them as many places as possible to avoid accidental damage or loss.

The microcomputer should insist on using the hard disk to guide, if necessary, only use their own non-toxic system floppy disk or CD-ROM to guide. The write protection port of the system disk must be affixed. You must insist on using no other floppy disk to boot, when necessary, also need to check the disk virus, confirm no virus.

Do not lend your own program to others. When you need to borrow a tray. A copy should be lent and the disk reformatted after it is returned.

Put all the COM and EXE formats in the file bin to "read Only" property to prevent viruses from invading people.

Many game discs have been illegally copied with a punitive virus, so workers are not allowed to use a variety of game software to calculate hunger.

For system parameters, such as boot sector, interrupt vector table, application length, execution time and so on, should pay close attention to, regular inspection. Find out the anomalies and get back to normal.

Once the computer system suffers from the virus, should report the unit's safety management personnel, as soon as possible inspection, clearance and recovery. It is believed that as long as the serious and responsible, can reduce the damage to the lowest degree.

Computer viruses, computer hardware itself and human beings are likely to pose a threat to computer security, so it is necessary to maintain the security of computers. Correct use and safety maintenance of computer hardware

(1) Display of the use and maintenance

Don't adjust the brightness too high.

The monitor should be kept at a certain distance from the operator.

Do not wipe with a damp cloth while the monitor is working, because there is a high voltage inside the monitor.

The monitor should avoid excessive vibration when working.

Do not let the strong magnetic field close to the monitor, do not let chemical solvents contaminate the monitor.

(2) The use and maintenance of hard disk

Large hard disk capacity. Fast, so the average user will be the application, System programs and data files stored on the hard disk. The maintenance of hard disk is a very important work.

Avoid the vibration of the hard drive, do not move the host when the hard disk is working.

Keep the environment clean, such as taking dustproof measures.

Develop a good habit of backing up your data and programs, and back up your data and programs on your hard drive.

Hard drive low-level format, hard disk partition, hard disk Advanced format command to use carefully.

(3) The use of floppy disk and male protection

Do not read and write to the floppy disk. Pull it out of the Luo actuator.

The floppy disk should be kept in clear sell. Do not touch the bare part of the platter with your hands, and then install the person's box.

Disc to prevent folding, magnetic, pressure-resistant.

It is best to back up the floppy disks that are playing with the content. and add write protection.

(4) The use of optical discs and male protection

Do not label on the disc. Lest the disc lose balance when rotating at high speed.

Do not force the disc to eject when the disc is working. Because the disc is at a high speed spinning state. It is possible to damage the disc halfway out.

Avoid the disc from direct sunlight. The reflection layer of the disc that prevents the disc from deforming and storing the data is damaged.

Do not touch the surface of the disc, so as not to affect the reading effect.

(5) The order of opening and shutting down the machine

Because the system in the power-on and shutdown of the instant will have a larger impact current. So power up the monitor first and then give the printer power. Finally, the host is turned on. Shut down the host before shutting down the computer. Turn off the external devices again.

Do not turn on the computer immediately after shutdown, to the next boot time between the bowel at least 10s.

The special note is that. Before shutting down your computer, be sure to shut down the application software and the system software properly.
