today AVIRA reported the file sdwelcome.exe as infected:

In der Datei 'C:\Program Files (x86)\Spybot - Search & Destroy 2\SDWelcome.exe'
wurde ein Virus oder unerwünschtes Programm 'TR/Crypt.XPACK.Gen' [trojan] gefunden.
Ausgeführte Aktion: Zugriff verweigern
Translation: In the file ... SDWelcome.exe a virus or unwanted program 'TR/Crypt.XPACK.Gen' [trojan] was found. Action applied: deny access

According to AVIRA "TR/Crypt.XPACK.Gen" is the following:

A generic detection routine designed to detect common family characteristics shared in several variants. This special detection routine was developed in order to detect unknown variants and will be enhanced continuously."

Is this a false positive of AVIRA/conflict between AVIRA and Spybot or anything to be concerned about?
