This file, found in Documents and Settings\All Users\Application Data\PrevxCSI, is currently flagged by AVIRA and Panda. I've submitted to AVIRA, but can't find where to send to Panda just yet. Update: now submitted to Panda.
Hello, This file is technically not a FP - it is our quarantine database with the copies of threats which Prevx has removed. The files are disabled and encoded using a simplistic algorithm which some AVs do decrypt and detect, even though the files could not possibly execute or harm your system. It is safe to add this file to the ignore lists of the other vendors
AVIRA have replied saying they've determined the file to be a false positive i.e. not malicious, but a false alarm.
