You must tell facts from fiction; viruses need living cells to replicate, because they do not have the molecular machinery at hand to generate energy and construct building blocks essential to life. So no, viruses cannot bring back the dead or revitalize dead cells.
The thing that comes close to it are zombie ants. These ants have been infected by a parasitic fungus that can take over the ant's nervous system (Fig. 1).

These fungi eventually kill their hosts, but before doing so they temporarily take over their nervous system. In the case of Ophyocordiceps unilateralis (Evans, 2011), the spores lodge themselves into the ant's head through an exposed part of the ant’s exoskeleton. The fungus then infiltrates and targets the ant’s brain, taking control of the ant. Then it makes the ant leave its colony and head for a leaf that provides the ideal conditions for the fungus to grow. The ant crawls under the leaf and goes into a “death grip”—biting down hard on the leaf's major veins. This allows the fungus to slowly feed on it. When the fungus finishes growing, it eventually kills the ant and releases its spores (Source: Smithsonian).
The interesting thing is that the zombie ant not only provides shade and humidity when hanging under the leaf, it is also positioned directly on top of the ant’s colony, so when the spores burst out they fall on other ants and begin the cycle all over again. There are hundreds of mind-controlling fungi like this one, but the chances of this type of parasitoid fungus evolving to target humans as hosts are unlikely (Source: Smithsonian).
