DiskImage is a tool to backup and restore partitions, entire harddisks, usb keys, floppy drives and (read-only) optical media on windows platforms. Built-in zip and libz compression, MD5 and SHA1 checksumming, a hex editor and more.
Still very useful app. I use it every so often. @hastalacoronill that .dll file is not a virus but a disassembler. Don't cry wolf if there is no issue at all. And your virusscanner reported it as 'heuristic'.. I assume you wanted to be helpful but please double check your results...
