Hi Raushan_india! It sounds to me that what you're experiencing is called a Parry. The icon is different and is a shield shape instead of a regular spiral.
Some conditions of Arena will allow your opponents to use the Masteries they have set up, so if your opponent has acquired Parry, then you'll be up against it in your fights.

I hope this helps!
