Hello, CH.

I have a networking problem with my computer.
Many of my programs can't access the internet, such as online installers and such, even when I run them as administrator.
Web browsers and Torrent clients still work, however.

I have not made any intentional changes to my computer, and have done a thorough virus scan with MBAM's most updated database.

As seen in the picture below, I was attempting to REINSTALL mingw-get. However, it was not ABLE to connect to the internet.



In this picture, I wrote a SHORT program to fetch Google's logo.
The first output is the return value of the URLDownloadToFileW from the Urlmon library.



If you have an idea of what is wrong, please tell me.
Thank you for the help.

Edit: This is the final log for the MinGW installer:
