I just have downloaded (from your website) and installed the newest beta 4.05.4. While doing so Avira Antivir 12 told me it found a virus/malware and tried to delete the file "partycommunicator.pt4" (I think that was the exact filename, but I'm not 100% sure). I assume everything is ok with the file, but I hope you will look into this.
I guess the file is only used for Partypoker, so can I play on Boss with this file blocked for the time being?
