Q: My computer encountered this problem a few days ago. Why can I access some websites with IP addresses but not with domain names?

A: This is because of a dns domain name resolution problem. Most of the reasons for this failure are due to a problem with the DNS server of the ISP service provider, or related restriction settings. Of course, sometimes it is caused by a failure of the local DNS cache. To speed up Website access, the system automatically saves a website that has been accessed and obtained an IP address to the local DNS Cache. Once the website is accessed again, the IP address of the website is not directly retrieved from the cache through the DNS server for access. However, sometimes the failure of Website access is caused by a problem in the local DNS cache. In this case, run cmd.exe, enter the Command Prompt window, and run the following command: ipconfig/flushdns. In this way, the Windows system will recreate the local DNS cache, and the problem will be solved.

Q: In IE Security Settings, I set the "Download Signed ActiveX Control" option to "prompt". Why are some Actives controls still inexplicably installed?

A: Actually, since it is set to "prompt", IE still has the privilege to download and execute programs without prompting. This is a serious security problem, and we may be completely controlled by others without knowledge. We can avoid such security risks by modifying the registry. Create a CLSID-based New {6E449683-C509-11CF-AAFA-00AA00 B6015C} for Active Setup controls in the Registry HKEY-LOCAL-MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ ActiveX Compatiblity }. create a value of the REGDWORD type: Compatibility Flags 0x00000400.

Q: I don't know what virus has happened on my computer recently. I keep popping up a webpage window, which is very troublesome. How can I eliminate such malicious harassment?

A: First, A "Suspicious file scanning tool" of Kingsoft, and then A Suspicious File "Msinfo. DLL "(many malicious websites use this file as an exception). The file is located in C: \ Program Files \ Common Files \ Microsoft Shared \ MSsearch \ bin \. Open the corresponding file and check it, "Msinfo. DLL is a hidden system file. After checking the information on the Internet, you can find that this file is an advertisement or a spyware file. Next, open the Registry Editor and find MsInfo in the registry. after the dll deletes the sub-keys that contain this field, restart the machine and delete MsInfo in the C: \ Program Files \ Common Files \ Microsoft Shared \ MSsearch \ bin \ directory. after the dll restarts the machine, delete "Msinfo. DLL ", and finally clear the buffer and history of IE, it will be removed from the root.
