NIS blocks idm519.exe

Hi,

I have recently bought a laptop and NIS (60 days trial came with it). It got win 7 OS.

I downloaded a zip file for Internet Download Manager. When i tried to extract it. NIS gives the message.

The file is blocked. It shows it as a High Risk File . Trojan.Gen. The file is idm519.exe. It is for installing the IDM.

I have installed this file on other computers. But they work just fine.

 

I tried a lot to retrieve the file but i cant. Please Help.

I really want to run that file. how can i get past NIS to get it??

how can i tell NIS  not to block a particular file??

 

Please Reply.

 

Thanks
