Thank you posting on Intel Wired Ethernet community.
Currently, we only moderate in English language and Wired product on this community. Therefore we suggest that you write your concerns in English in order to better collaborate with other members of this community. If you desire to speak to an Intel Customer Support representative in your native language, please click on this link Contact Support.
For the meantime, I will forward your concern to the Wifi support group.
According to our translation, we understand you can no longer connect to the Internet using your PC with the Intel® WiFi Link 1000 after installing a Microsoft* security application. Our first recommendation would be to contact Microsoft* in order to check this application settings and see if there is anything on its configuration that can be done if it is really necessary to have this application running on your computer in order to fix it.
Another option would be to contact your computer manufacturer: Computer Manufacturer Support Websites and re-download the drivers from their support. If after you trying their drivers and you still can't detect the drivers, you can try our generic drivers found in our download center, here is the link: Download Intel® PROSet/Wireless Software and Drivers for Windows 7* file name: Wireless_18.12.0_s64.exe
