Onkohan kyseessä db-tiedosto?
Jos olet tarkastanut ulkoisen kovalevyn virusten varalta eikä mitään löytynyt, miksi se pitäisikään poistaa?
Edelleen Wikipediasta:
On Microsoft Windows operating systems, a thumbnail cache is a file used to store thumbnail images for Windows Explorer's thumbnail view. This speeds up the display of images as the smaller images do not need to be recalculated every time the user views the folder.

Windows stores thumbnails of graphics files, and certain document and movie files, in the Thumbnail Cache file, including the following formats: JPEG, BMP, GIF, PNG, TIF, AVI, PDF, PPT and HTML. Each thumbnail created in a directory is represented in this database file as a small JPEG file, regardless of the file's original format. The images are resized to a maximum of 96×96 pixels, or a proportional miniature of their original shape for non-square images, with 96 pixels on the longer side. Each folder with initiated thumbnail views (that is where they have displayed a Thumbnails or Filmstrip view in Windows Explorer) will have a Thumbs.db file. Folders with pictures also display previews on their icon when displayed in Thumbnail mode – the first four images in the folder at 40×40 pixels (or proportionally shaped), with a 1-pixel divider overlaid on a standard large folder icon.
