Because Windows is widely used, it has become the target of hackers. as Trojans and viruses emerge, it is especially important to prevent them from getting started.
Prevention of fire
The simplest and most effective method is to install anti-virus software and update the virus database from time to time. Then, install necessary patches for the Windows system through Windows update, which can also prevent viruses and hackers. It is also important that you do not access suspicious websites or download software of unknown origins. when visiting a website of unknown origins, you must see the pop-up window prompts, if you want to install software or other risky operations, click "yes" as soon as the pop-up option is displayed ".
Good backup habits can minimize loss in case of accidents. If it is too difficult to reinstall the system, you can use ghost to back up a clean system. This is also a simple method, however, "favorites" and "My Documents" folders containing personal documents should also be saved.
The virus is not terrible.
When the computer shows signs of poisoning, look at some tricks of the network administrators. If you have mastered these skills, you can handle the computer viruses on your own.
Tip 1: Press Ctrl + Alt + DEL to call up the task manager, check for unfamiliar suspicious programs and processes, and select these programs and processes to stop them with the speed task or stop the process. Then try anti-virus software.
Tip 2: Check whether any strange item exists in the Windows startup Item. You can go to C: Documents and SettingsAll UsersStart MenuProgramsStartup or C: documents and Settings check whether there are suspicious files in the \ Start MenuProgramsStartup folder named by the current user name (note that the attribute files are hidden ).
Tip 3: Start-run-msconfig. Here you can view the important files system. ini, Win. ini, and Boot. ini, as well as all system services and startup items. Msconfig first appeared in Windows 98, but it was somehow saved by Microsoft when it arrived at Windows, until Windows XP appeared again in the system. If you are still using Windows 2000, copy msconfig.exe from Windows XP to any path in Windows 2000.
Tip 4: Start-run-Regedit and go to HEKY_LOCAL _ MACHINE_Software_Microsoft_Windows_Currentversion_Run to check items with unknown routes.
Tip 5: Open c: autoexec. bat and c: config. sys in notepad and check whether the file has been changed.
I believe that, after making these five moves, the virus is hard to hide.
