Clear the stubborn pop-up window

under Windows XP SP2. My system is XP (SP2) with all patches, the anti-virus software is Jiangmin KV2005, and the pop-up window blocking function of 3721 Internet Assistant is enabled, which can be used when the machine opens the normal webpage recently. Inexplicably popping up a window titled "mms.tjcq2.com", I thought it would be very simple, it can be used to search the registry and fix IE, it is very annoying! Finally, I searched for two solutions on the Internet and did not dare to enjoy it. Method one:
Disable NaviHelperObj Class in IE's "Tools" = > "Manage Add-ons". After using IE for such a long time, I don't know if there is such an option. 惭愧 Method 2:
1. Start menu = > Run => Enter "regsvr32 NaviHelper.dll -u" 2. After restarting, delete "NaviHelper.dll" and "Host.dat" under Windows\\system32
