On a machine with a low computer configuration, it is certainly much more efficient to not install anti-virus software. I have no anti-virus software for more than two years and there is no reason for virus infection. To put it bluntly, you are online as a user! Not an administrator. Let's talk about how to access the Internet in user mode.
1. After installing the system (including Ghost XP), it is very important to first convert all partitions to NTFS format. Don't say no, just click the start button -> Run. Enter "convert c: /fs:ntfs" to convert the C drive to NTFS format, but you need to reboot to convert it. Other disks will change C to the corresponding drive letter.
2, open the "user account" in the control panel, the Administrator to change the password, as much as possible, do not have to remember. Create a computer administrator user and a restricted user. The administrator user must have a password and be more complicated. This password should be remembered. Because the software is installed later, the game will be used. Of course, I can't remember to change it under DOS.
3, after setting, enter the created computer administrator user, open "My Computer", click "Tools" -> "Folder Options", click the second tab " Check ", remove the checkmark from "Use simple file sharing (recommended)" inside. This is the "Security" tab that appears when you open the properties of a folder or file later.
4. Remove the "users" user from the "Security" tab of all partition properties. This is because it has a special permission by default, you can create a folder under the partition or folder, and then you can create or save a file, which may give the virus a chance. So get rid of it. There is also one "everyone". Also removed. Add the created restricted user into it, the permission is "read only".
5, the permissions of individual files: like QQ, games need full permissions, so in the computer administrator users to give limited users full access. QQ is best to give the read-only permission to the files together with the QQ program, to prevent the Trojan from replacing QQ and related DLL files.
6. Enter "REGEDIT" in "Run", open the registry, and put [HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Run] or [HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\ The permissions of CurrentVersion\\Runonce] are set to read-only. Prevent viruses from starting here.
7, clean up the Internet cache and temporary files, when surfing the Internet, the general cache is placed in C:\\Documents and Settings\\username\\Local Settings\\Temporary Internet Files, this is also the place where the virus is hidden, also There is a temporary file under C:\\Documents and Settings\\username\\Local Settings\\Temp. Many programs use this place. The virus also likes to hide here, so when booting up, use the batch command to empty the two folders. Let the virus have nowhere to hide. The batch command is:
del C:\\docume~1\\username\\Locals~1\\Tempor~1\\*.*
del C:\\Docume~1\\ Username \\Locals~1\\Temp\\*.*
Of course, both History and Cookies can be emptied.
Make a batch command file and put it in the "Start" item in the Start menu.
This will also be a preparation for the limited users to access the Internet. The virus on the Internet can no longer infect your system, nor can you change the system files, and you have no right to change other partitions. It doesn't matter because the virus can't be written to the partition root. The web virus can't change the system file, and the vicious web virus can't do anything about it. Of course, this method is not suitable for people who install software madly. If you want to try software, if you don't install anti-virus software, it is best to use virtual machines like VMware and Virtual PC. For music or movies only, it has no effect. Tr
