If you uninstall according to the conventional uninstall method and set the local security policy, it is recommended that you block 360, so you don’t have to worry about the possible residual programs of 360 running secretly. The specific operations are as follows:

1. Import the registry information file CodeIdentifiers.reg to enable executable file certificate rules. Import method: Double-click the file icon and select "Yes" to confirm adding to the registry.

2. Create a software restriction policy

Enter the control panel (win7 switches to small icon view, XP switches to classic view), enter the management tools-Local Security Policy, right-click Software Restriction Policies - Create software restriction policies. (You don’t need to create it again if you have created it before)

The following steps can only be performed under win7 (XP users please ignore it)

Right-click Force - and select Properties

After entering the properties, select the mandatory certificate rule and click OK (ignore the warning)

The above is the preparation for blacklisting 360. The specific operations for blacklisting:

1. Obtain the latest digital signature of 360

The latest one is 360.20130316.cer. There is no need to obtain it separately, but it needs to be obtained again after March 2013.

2. Create a new certificate rule and block 360 digital signatures

Enter the control panel - management tools - local security policy - software restriction policy - other rules, right-click in the right sub-window and select - Create a new certificate rule.

Browse to select the latest digital signature certificate from 360, and set the security level to Not Allowed.

3. The security policy will automatically take effect after restarting the computer.
