Windows Defender is a security product developed by Microsoft which provides ultimate security and protection regardless of the version of Operating System used. Windows Defender can protect users from all kinds of security threats like online malware attacks and offline media related threats. Windows Defender is built to detect large number of known viruses including Trojans, adware, spyware, etc. Windows Defender would block all possible threats at the initial stage, providing better security than traditional Antivirus tools.

In such a case, you need to lower the security setting of Windows Defender. Windows Defender may also have issues related to configuration. So, you can reconfigure the settings of Windows Defender.
Windows Defender corrupt
Windows Defender may get corrupt in certain cases. Windows Defender connects itself to the Internet automatically. Sometimes, during update process, there can be issues with ‘dll files’ which may block the Internet. The corrupt Windows Defender needs to be reinstalled. You need to uninstall Windows Defender completely, then reinstall it again.
Sometimes, the Windows Defender may be installed properly and still you may be unable to access the Internet. The main reason of this problem is DNS patch. That is, DNS queries are not sending data from constant UDP port in a limited range. A random port is selected for replying to queries and your firewall software may block this action. That is, a firewall software may block queries, which are not recognized. So, you can turn off the firewall to work on the Internet.
