The first method is: to use QQ and 360 synchronously. Since 360 can be used directly without installation, we can copy the already installed 360 directory and store it in another place, then uninstall the 360 product, and then directly run the 360 directory product that we have copied. This way, QQ and 360 can be used simultaneously.
The second method is: to solve the problem of QQ and 360 not being able to run at the same time:
1. Locate the QQ security component.
1) Under the XP system: C:\Documents and Settings\Administrator\Application Data\Tencent\QQ
