What to do after reinstalling the system to completely prevent the virus

The virus has always been a problem for everyone. I believe that many people choose to reinstall the system because the computer poisoning is too deep, but it is not known that there is still a virus after reloading. Many people think that as long as the operating system is reinstalled, the virus can be completely eliminated. However, I don't know that after the operating system is reinstalled, due to security settings and patches not being installed in time, it is most likely to cause a virus to invade. Therefore, some necessary supplementary measures are very important.

First, don't rush to access the network

After installing Windows, don't immediately connect the server to the network, because the server has not been patched and there are various vulnerabilities. Very vulnerable to viruses and intrusions. At this point, you need to add a patch and restart it to connect to the Internet.

Second, patch the system /install anti-virus software

Installed the Windows XP SP2 patch. After installing the system, be sure to install anti-virus software and update it to the latest version.

Third, turn off system restore

System Restore is a feature in Windows ME and Windows XP, Windows 2003, which allows us to restore the system to a certain time state, thus avoiding us to re- Install the operating system. However, some people after the system restore, found that in addition to the C drive, the other D drive, E drive are restored to the previous state, and the results of the saved files are gone, causing serious losses!

This is because the system restore defaults to all partitions on the hard disk, so once the system restore operation is performed, the data of all partitions will be restored. Therefore, we must press the Win+Break button, then click the “System Restore” tab, uncheck the “Resume System Restore on all drives” option, then select the D drive and click the “Settings” button. In the window that opens, select the option to "close the system restore on this drive".

Then turn off the system on other disks in turn. In this way, once the system is unstable, you can use the system restore tool to restore the system on the C drive, but at the same time the files on other disks will not be a problem.

Fourth, give the Administrator a password

Some people may use the online download of the universal Ghost version to install the system, or it may be using the Windows XP unattended installation CD installation The system, when using these methods, is most likely not to let you specify the Administrator password, or the Administrator password is the default 123456 or simply empty. Such a password is quite dangerous. Therefore, after reminding everyone to install the system, please right click on "My Computer", select "Manage", and then select "Computer Management (Local) & Rarr on the left side; System Tools & Rarr; Local Users and Groups & Rarr; Users & rdquo;, select the Administrator in the right window, right-click, select “ Set Password & rdquo;. Click the “Continue” button in the open window to set the password for the Administrator in the open window.

Also, select “new user”, set the username and password, double-click the new user, click the "subordinate to" tab, select all the groups (if any), click Below the “delete” button. Click the “Add” button, and then click the “Advanced” button in the open window, then click the “Find Now” button to find the PowerUser or User group, click “OK” Times, add this user to the PowerUser or User group. Logging out the current user and logging in as a new user can reveal that the system is much faster.

V. Turn off the default share

After the Windows installation, some hidden shares will be created, which are mainly used when the administrator manages the system when logging in remotely, but for individual users, this is rarely It is not very safe to use. Therefore, we need to cut off this share: first create a new disshare.bat file under d:, write the following statement in it:
