Windows Security Issues Prevention and Handling Talk

Security Code show

A: Follow the genuine virus software and update the virus database from time to time, and turn on the firewall when using the system. Regularly check the system for anti-virus and anti-virus, in the case of suspected exposure, use a variety of genuine anti-virus software under Windows and dos cross-virus.

B: Make a backup of the C drive with ghost, and use KV, PQ and other software to back up the hard disk partition table. At the same time, you need to make a boot disk to use if necessary.

C: Do not download software or hacking programs from unknown sources on the Internet or D-disc. Try not to go to sites with security risks, such as “Y” Sites. Try to install the latest OS
and browser, and upgrade the system by downloading and installing patches.

智智病毒

A virus is a destructive piece of program or code that is fired when the computer
meets its operating conditions. And computer
will produce the following conditions:

The computer crashes from time to time; the system suddenly restarts; the hard disk light flashes and you do not perform any read or write operations at all; the system is frequently wrong, illegal Operation prompts constantly ……

At this time, don't panic, first use Ctrl+Alt+del to call up the task table. See what programs are currently running. Once you find a strange program, terminate the operation with the end task. Then, look for anti-virus software to kill. In the absence of anti-virus software, I hope that friends can do the following:

1. In the start --- run sfc, check the system file for changes.

2. Once you find an exception, check if there is a strange program loaded in the startup group of windows. The path is c:windowsstarmeanprograms, you should pay attention to the hidden files (after the operation on the toolbar) You can see hidden files: View - Folder Options - View - Files and Folders - Hidden Files - Show All Files)

3. Open the registry (win+R) and enter HEKY LOCAL MACHINESoftwareMicrosoftWindows
CurrentversionRunServices and Run look at it, such as finding such a stuff: C:WINDOWSSYSTEMKernel32.exe, congratulations to you - in the glaciers, huh:)

4. Using Notepad Open c:autoexec.bat and c:config.sys. These two files record the driver information required by the system. If you find a strange program in it, del first.

5. Similarly, what is in the c:windowssystem.ini, find the [386Enh] column, take a closer look at what is behind the device=”, if it is some system The required driver files, such as: device=vmsgd.vxd and device=vpbiosd.vxd, are nothing, but if there is doubt, you don't have to hesitate. It is best for friends to back up the relevant documents in advance.

6. Enter msconfig in the run, click win.ini, click [windows] below, you will see the following 2 lines: load= and run= This is the program that is automatically executed after Windows starts. At the same time, the virus also likes to add something after load and run:)

Processing "Unsafe"

Once the windows system is destroyed or crashes, how should friends To cope with the maximum protection of the system security? I thought of the use of windows comes with the boot menu method, the operation is as follows: after the computer self-test, quickly press the F8 key, enter the windows boot menu:

1.Normal: Start win98 in normal mode and use it under normal conditions.

2.logged(BOOTLOG.TXT): Open the C:?ootlog.txt under the dos with the edit command to see if there is an Error or Fail header. This part is where the window error occurs.

3.Safe Mode (shortcut: F5): Start win98 in safe mode. The so-called security mode is that the system starts to configure only the mouse, keyboard, VGA display, non-accessible optical drive, no Internet access, no peripherals. This will troubleshoot the system at its lowest operating state.

4.Step-by-step confirmation (shortcut shift+F8): This is a step-by-step start of win98, Enter key to confirm.

5.Command prompt only (shortcut shift + F5): Normal startup (loaded config.sys and autoexec.bat) directly into the MS-dos mode, you can also enter win98 through the following command:

win/d:m Enter in safe mode

win/d:n Enter in safe mode with network function

win/d:f boot is forbidden 32 bit Access (probably to avoid hard drive failure)

6.Safe mode command prompt only: Starts into Ms-dos in safe mode, and can completely kill the virus in this state.

Making data safe

Windows vulnerabilities have caused inconvenience to friends, at this time. Friends can use the excellent software such as the optimization master to perform the WYSIWYG hiding and permission setting on the system. You can also perform the following operations to ensure the security of the data:

A: Enter the drive, use Drag the mouse to drag all the files, right click, select Properties in the pop-up menu, set the properties of the file as read-only and hidden, and click Apply.

B: Click on the <quo;View”-“Customize Folder”-“Select Create or Edit HTML Document> on the toolbar to be protected, and click Next. Next, in the source file edit box of Folde.htt, press ctrl+A to select all, and then press the del key (or add a java script that requires a password in the body area. The prompt can be set as: the system is illegally invaded , will be automatically turned off after 10 seconds: o). Next, save the changes you just made.

C: Oh, congratulations, protection is complete, for the owner, just use the Select to view, folder options, view, select all files (not set to show hidden files or systems when not in use) File), at the same time, don't forget to cancel the view by web page, otherwise you can't see anything! (If you don't need to choose to view by web page)
