I downloaded and installed this on a spare machine in my network, just to have a look at it. I have one curious issue, which maybe is normal. On every drive that has been scanned, there is a AVG6DB_F.DAT file. This appears to vary in size, based on the number of files on the volume, so I'm assuming it's some sort of index or what? Does anyone know what the purpose of these files are? I didn't see anything in their FAQ for the program on the website.
