Though there are many programs out there to help you,i would be a little concerned if you run these on your network and the IT staff are supposed to mantain the systems.
However,if you wish to try and rid your system of this,try:
Asquared click here
Trojanhunter click here
Superantispyware click here
Spybot Search and Destroy click here not the Beta version,select another version.Sorry i cannot recommend a Beta product though all may be ok.
