Is this a false positive? Win32:Agent-ADVJ [Rtk] in SAS

[sanjayen]

I did a complete scan of my laptop using Avast (updated definitions) and it found a trojan - Win32:Agent-ADVJ [Rtk] in the SAS file SUPERANTISPYWARE-6-27-2009( 14-15-13 ).SDB inside the SUPERAntiSpyware.com\SUPERAntiSpyware\AppLogs folder.

Is this a false positive from Avast? Or was my laptop already infected? Please do let me know.
