Hello, you said you have uninstalled other security software, so may I ask if you also uninstalled the programs associated with it? One of the security software generates a security component that is not visible in the control panel programs and features. I suggest you check if there is a C:\Program Files\Common Files\Baidu\BaiduProtect\version number folder, and if it still exists and you can find an uninst.exe in it, then double-click to uninstall it.
If it does exist, after uninstalling it, you can reboot into Safe Mode, delete the C:\Program Files\Common Files\Baidu folder, and reboot your computer.
If you confirm that this security component has been uninstalled, but you are prompted to run Tencent's PC Manager without proper access rights, you can also do some general troubleshooting.
I don't know what your operating system is, if it is WIN7, you can right-click on the installation folder of PC Butler, select Properties, click on Advanced in the Security tab, click on Change Permissions, clear the Permissions that can be inherited from the object's parent checkbox, select Administrators, click on Edit, and select Replace Sub-Object Privileges with Privileges that can be Inherited from this object. check box.
For WIN8, also in the folder properties of the security tab, click Advanced, click Change Permissions, check Replace all child permissions with permissions inherited from this object, check Administrators, click Edit, and check Full Control. If the Edit button is not available, then click Disable Inheritance to change it to Enable Inheritance to change it.
If that doesn't work, expand Application Control Policy/Applocker in Control Panel/Administrative Tools/Local Security Policy. /Applocker, see if there are any rules on the right side, and if there are, right-click and select Delete.
