A potentially dangerous Request.form value was detected from the client

Question

What is this and why am i getting it when i try to login to my website? It looks like form injection warning but from where,how, and why. My computer doesnt have a virus or malware (that i know of) Im running an almost brand new mac os x 10.9 and the browser im using is Google Chrome.

The full error message is as follows:

Error Message: A potentially dangerous Request.Form value was detected from the client (h_rm_pgs_ClientState="...rialGirls'","value":"1695...").

Where is this coming from and why?

Trace sent values by Google Chrome. Just right click and select Inspect Element then go to Network and after that open target page to trace and understand what happened.

I guess it happens when your browser has unwanted plugins or additional tools in your computer. Good Luck.

I'm guessing you have a password that contains "<". ASP.NET returns that message from it's request validation in an attempt to stop XSS.
