By the way, I have downloaded A2 uploader, but have not used it for anything yet. However, Symantec Antivirus reports that it is a trojan horse, and has quarantined it.
I posted about this this past weekend. Antivirus programs will view A2Uploader as a virus. You'll need to turn off your antivirus program before you can use the uploader program. And, if yours has put it in quarantine, you may need to download it again after you've deactivated the antivirus.
