Is there any relation between bacteria and virus genetically? How long I know, bacteria is with life and virus is in a middle position between life and material.
Depends on your point of view.
In some cases, the genomes of cells include left over viral DNA which becomes "trapped" due to mutations of nearby genes changing the starting and ending points of those genes. Chunks of viral DNA can become incorporated in the DNA of a bacteria or vice versa (spell check fail). The same can also be potentially true for prions.
Some nuclear DNA may actually be indistinquishable (spell check fail,) from being a beneficial symbiotic prion. i.e. gut bacteria gene being "spliced" in nature and conveniently incorporated in a Beetle's own DNA, enhancing it's digestive system.

In the common sense, no. They do not share a common line of decent. Above, Quantum Conundrum is referring to
Horizontal gene transfer. The same relationship works both ways, however, because viruses are little more than DNA fragments that evolved into a parasitic form. Those fragments could have originated in any number of organisms.
