Narrative:

While descending we were cleared for the ILS for runway 7 and ATC told us that there was VFR traffic to our north and that it was unverified. We told ATC we were looking for traffic. ATC then advised us that frequency change was approved so we could monitor CTAF frequency since this is an uncontrolled field. We had been cleared direct to the FAF and cleared for the ILS 7. We made our initial calls on CTAF trying to reach the VFR traffic. They were initially north of the approach and I though they were doing maneuvers. We then heard the traffic state they were turning inbound on the procedure turn for the ILS 7. I guess they were practicing approaches while VFR. This is the time we noticed that they were turning inbound right towards us. We were now just over the FAF and the traffic was on a dangerous course towards our aircraft. To prevent a collision the captain turned to the south to avoid the VFR traffic and said we will have to make a 180 degree turn to let them clear us so we would remain clear of the VFR traffic. As soon as time permitted I made a call to center and told them what had happened. The rest of the approach was uneventful. This is one of the dangers associated with flying a jet aircraft into an uncontrolled field while in VFR conditions. There are many small very slow aircraft in the area that don't need to be talking to center and do not make frequent CTAF radio calls
