After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".
After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later.
