So, you have installed Microsoft Visual Studio 2005/2008, created a Web Project using the ASP.NET Development server, hit F5 and you are greeted with this:
Internet Explorer cannot display the webpage.
This is NOD32′s fault.
Set the NOD32′s control panel to advanced mode.
Go to Setup->Antivirus and antispyware…
and click on Web Access protection->Configure…
Select "HTTP and POP3 ports" in the Protocol Filtering section.
