Difference:
Viscous force depends on the velocity gradient and area of contact and frictional force independent of area of contact and relative velocity.
 
Viscosity of liquid decrease with increase in temperature, Where as friction independent of temperature.
In friction heat is generated at the surface between the solids. When a fluid       moves over a solid heat is generated within the fluid.
