Tips for preventing system intrusion without anti-virus software

1. After installing the system (including ghostxp), it is very important to convert all partitions into NTFS format. Don't say no, just click the start button --> Run. enter "convert C:/Fs: NTFS" to convert drive C to the NTFS format. However, you must restart the drive to convert the drive C to the correct drive letter for other disks.

2. Open "User Account" in the control panel and change the administrator password as complicated as possible. create a Computer Administrator user and a restricted user. The administrator user must have a password, which must be kept in mind. because later software is installed, the game will be used. of course, I can't remember how to change it in DOS.

3. After setting, go to the created computer administrator user, open "my computer", click "Tools" --> "Folder Options", and click "View" on the second tab ", remove the check box before "use simple file sharing (recommended. The "security" tab will appear later when you open the folder or file attributes.

4. Remove the "users" user from the "Security" tab of all partition attributes. It has a special permission by default. You can create folders in a partition or folder. You can create or save files, which may give viruses a chance. So remove it. The other one is "everyone. Add a restricted user. The permission is read-only ".

5. Permission issues for individual files: QQ and games require full permissions. Therefore, the Computer Administrator must grant full permissions to restricted users. It is best to associate QQ with QQProgramThese files are read-only to prevent trojans from replacing QQ and related DLL files.

6. Enter "Regedit" in "run" to open the registry, set the permission of [HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Run] or [HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ runonce] to read-only. Prevent viruses from being started here.

7. Clear the Internet cache and temporary files. when surfing the Internet, the cache is generally stored in c: \ Documents and Settings \ USERNAME \ Local Settings \ Temporary Internet Files, which is also a place where viruses are hidden, there is also a temporary file under c: \ Documents ents and Settings \ User Name \ Local Settings \ temp. Many programs need to use this place. Viruses also like to be hidden here, so when you start up, use a batch of commands to clear these two folders. Hiding viruses. Batch command:

Del c: \ docume ~ 1 \ USERNAME \ locals ~ 1 \ Tempor ~ 1 \*.*

Del c: \ docume ~ 1 \ USERNAME \ locals ~ 1 \ temp \*.*

Of course, you can also clear both history and cookies.

Make a batch command file and place it in the "Start" item in the Start Menu.

In this way, the preparation for restricted users to access the Internet is ready. The virus on the Internet cannot infect your system, nor can you change the system files. You do not have the permission to change other partitions, in this way, the USB flash drive does not matter because the virus cannot be written to the root directory of the partition. Webpage viruses cannot change system files, and even malicious webpage viruses cannot.

Of course, this method is not suitable for anyone who installs software. To try the software, if you do not install anti-virus software, you 'd better use virtual machines like VMware and Virtual PC. It has no effect on music or movies.
