2. Pop-up web pages can be saved in the host. Once online, trigger the default URL and it will open automatically. Check the host: use Notepad to open the host in the directory C: \ Windows \ System32 \ Drivers \ etc \, check whether there is a URL in it, and delete it if there is one. Or add 127.0.0. 1 in front, and shield after saving.
3. When Windows2000/XP operating system is turned on, it will automatically start its own Messenger service, which can receive pop-up messages and send them to other computers. This function is exploited maliciously, which leads to the phenomenon that messenger advertisements are flying all over the sky. We can ban it in the following ways: select Control Panel → Administrative Tools → Services, find the "Messenger" item in the service window that appears and double-click, then select the General tab in the Messenger properties dialog box that pops up, change the startup type to "Ban" and click the "Stop" button.
