Avira's interesting detection

Today,when I ran garena.exe(A game platform client),Avira popped up saying pluginkernell.dll a virus(TR/PSW.OnlineGames.tsoe).I thought it was a FP.So I added the file to exception list.
Afterthat,I let Virustotal checked the file.Only these 5 AVs found it as a virus:
AVG(PSW.OnlineGames.BHAR),
F-Secure(Trojan-GameThief.Win32.OnLineGames.tsoe),
SecureWeb-Gateway(Trojan.PSW.OnlineGames.tsoe),
ViRobot(Spyware.PSW.OnLineGames.78848.C).
However,when I tried to start garena.exe again,OA popped up saying "GPE3.tmp by garena wants to start automatically with my computer.)I clicked "block" for sure.
Then I notice garena.exe was updating itself and the file it had updated was only "pluginkernel.dll".
So what I think now is THE OFFICIAL GARENA WAS INFECTED WITH VIRUS WHICH AVIRA DETECTED IT.
What do you think?

 

I checked Garena's forum.The administrator there has made a sticky thread saying their application is clean while some gamers still believe their AVs rathan the admin.It seems Kaspersky treated it as infected too.

 

Obviously Kav detects it too since the F-Secure detection is in the AVP format.

You can try uploading the file here:

In the file type select: Suspected False Positive (Not Malware)

 

Yep trust your Antivirus but to be sure, summit samples to Avira for analysis worst case senario a FP.

 

I forgot to send it there.I've updated the application so the virus seems gone by now.
