A dll infection, False Positive?

Dear Experts

“If a file is quarantined, the file goes to "safe vault". In other words you're "Clean" as the quarantined file cannot be accessed anymore which also means you're system is now clean from that infection”

I Installed Saitek Smart Technology Software (SST),
 
Prevx found a TREATH, I do not know if this is a FP

In C:\WINDOWS\Temp\Saitek\Saitek_Cyborg_V3_Pad_SD6_32_Software\00000010\
the dll setup_0a.dll is detected as malware, here is the Prevx Log:

Please note I did not include all the log is very large

If I add manually the infected .dll to Quarantine, and run Prevx then my System Status is clean

At this Thread, The Prevx Moderator, Inform me he fixed the FP

But my system status is still infected
 
I think i do not have a FP anyway
after the fix Here is my Prevx Log once again

As above I did not include all the log is very large

At this point I do know what to do; I sent another email to report@prevxresearch.com

Uninstall the SST
Hijackthis
Manually Quarantine the infected .dll
Online Scanner
Pray

Any suggestion, help, advice, ideas are more than welcome
