can you tell me ?from so many days when i make any folder .it makes shortcut icon .is it virus ?if so .can you tell me ?.how should i remove this virus ?

Honestly, I have no idea what it is that you are asking. Your attachment shows only a tiny icon that says PetrolPump which means nothing to me.
If you believe your computer is infected then you need to follow all the steps given in our Read Me First sticky and post back here with Copy/Pastes of all the logs produced. Do Not Attach any logs, Copy/Paste them please.

After you post all the requested logs then we can better tell what else needs to be done.
