NIS 2009 detects Trojan.Adclicker in symantec folder

NIS 2009 detected Trojan.Adclicker in the follow folder, along with 10 registry entries.

 

c:\program files\common files\symantec shared\support controls\ssctlbr.dll

 

I had just done a full system scan with Ad-aware and it had finished and was sitting on the final results screen.  NIS did an idle scan between the time Ad-aware finished and I came back to the computer.

 

Is this real or a result of Ad-aware?
