IE _browser = new IE();
_browser.GoTo(_url);
_browser.Eval("alert('hello!');");
I get the following error:

Malicious code : invoking eval can crash a computer. For example: if you use eval server-side and a mischievous user decides to use an infinite loop as their username. Terribly slow : the JavaScript language is designed to use the full gamut of JavaScript types (numbers, functions, objects, etc)… Not just strings!
eval() is a dangerous function, which executes the code it's passed with the privileges of the caller. If you run eval() with a string that could be affected by a malicious party, you may end up running malicious code on the user's machine with the permissions of your webpage / extension.
An alternative to eval is Function() . Just like eval() , Function() takes some expression as a string for execution, except, rather than outputting the result directly, it returns an anonymous function to you that you can call. `Function() is a faster and more secure alternative to eval().
If the data is comming from your server and its something that you, the developer has generated, there is no harm in using eval(). The real harm is beliving everything you read. You see lots of people saying eval() is evil and they have no idea why except that they read it somewhere.
Try turning off IE's protected mode or add your site to trusted zone.
