I am having a problem with image files like .jpg .tiff .bmp and others changing to 4gb in size, this is occuring only on the Data Vol. I have run Symantec Antivirus Corporate Edition 8.0 with the current definitions and have found no viruses. It started with just about 50 images and now has grown to around 3500 images. I know it sounds like a virus but for some reason I cannot find the source or the reason behind the growth...
