Browser launches automatically every 30 seconds

Hi Nikhil.
Since when are you experiencing this issue? Which web browser are you experiencing this issue with?
Does it just open a new tab or does it redirect you to any website?
Please check the list of installed applications on your PC and remove unwanted.
