Trojan warning when installing arduino create agent

Hi,

I'm new to this forum. I just bought an Arduino Uno R3 as an entry to learning some programming and electronics skills. I've fallen at the first hurdle in installing the windows plugin for the web ide. When I go through the process of installing Arduino create agent 1.1 I get a warning message from my antivrus.

Call me suspicious but I thought it better to heed this warning and halt the installation. Does anybody have any thoughts on why I am getting this message and whether I can safely disregard it?

I should add tht I have tried Google but could not find any reference to this.

I have attached a screenshot of the virus software warning.

Many thanks in advance.
