We all know that Windows is not a safe operating system, viruses, hackers threaten us from time to time, let's talk about Windows system security problem prevention and treatment methods.
A: According to the genuine virus software and update virus database from time to time, when using the system to turn on the firewall. Regularly check the system for anti-virus and anti-virus, in the case of suspected exposure, use a variety of genuine anti-virus software to cross-virus under Windows and DOS.
B: Use Ghost to make a backup of the C drive, 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, D version of the CD-ROM or download software from unknown hacker programs from the Internet, try not to have a security risk sites, such as the "Y" site and so on. Try to install the latest operating system and browser, and upgrade the system by downloading and installing patches.
reason for virus
virus is a program or code with a destructive, when the computer meet their operating conditions, the virus will be excited. The computer will produce the following condition:
computer crashes from time to time; the system suddenly restart; HDD LED flash and you did not perform any read or write operation; frequent system errors, prompt illegal operation continued ...... < BR>
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. This was followed by a moment without antivirus software, I hope you do the following points:
1. Enter sfc in the beginning --- operation, check whether the file system changes.
2. Once found to have abnormalities, look at windows startup group, there are no strangers to load the program, the path is c: Windowsstarmeanprograms started to pay attention to view hidden files, oh (subsequent operations 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 MacHINESoftwareMicrosoftWindowsCurrentversionRunServices and Run seen it, find this stuff such as: C: WindowsSYSTEMKernel32.exe, we must congratulate you - in the ice, huh :)
4. use Notepad to 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, enter c: Windowssystem.ini what stuff there, find the [386Enh] in this column, look at the "device =" What is behind the band, if it is necessary for some systems Driver files such as: device=vmsgd.vxd and device=vpbiOSd.vxd are fine, but if there is doubt, don't 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 automatically executed after Windows starts. At the same time, the virus also likes to add something after load and run:)
Handling "unsafe"
Once the windows system is destroyed or crashes, how should friends respond? To maximize the security of the protection system? I thought of the method of using the boot menu that comes with Windows, the operation is as follows: After the computer self-test, quickly press the F8 key to enter the Windows boot menu:
1. Normal: Start win98 in normal mode and use it normally.
2.logged (BOOTLOG.TXT): Open in DOS using the edit command C: ootlog.txt Error or Fail to check the prefix, this part of the window is the wrong place.
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 to start win98, Enter key.
5.Command prompt only (shortcut shift + F5): normal start (the autoexec.bat and config.sys loaded) directly into MS-DOS mode, may be entered win98 by the following command:
win/d:m Enter in safe mode
win/d:n Enter the security mode with network function
win/d:f Start is forbidden 32-bit Access (probably to avoid hard disk failure)
6.Safe mode command prompt only: Start in safe mode to enter Ms-DOS, you can thoroughly kill the virus in this state.
make data security
Windows vulnerabilities to friends inconvenience, then. Friends can use the excellent software such as
Optimization Master
to make the WYSIWYG hidden and permission settings of the system, and also can perform the following operations continuously to ensure the security of the data:
A: Enter the drive, drag all the files with the mouse, right click, select properties in the pop-up menu, set the properties of the file as read-only and hidden, and then click Apply.
B: Click "View" - "Customize Folder" on the toolbar to be protected - "Choose to create or edit Html document", press Next, then next, in the pop-up 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, after 10 seconds Auto off: 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! (When you don't need to choose to view by web page)
