The hand sanitizer abuse is only an issue insofar as it reduces our exposure and doesn't allow our immune system to build memory.
Chances are that a strain that evolves resistance to sanitizer won't simultaneously evolve resistance to antibiotics. In the absence of these selective pressures, we tend to see a loss of these traits because they are energetically expensive, and these strains tend to be outcompeted by those without these particular metabolic constraints. Have we seen strains that have both antibiotic resistance and show resistance to hand sanitizers? I honestly don't know, but I think it would be extremely rare, and would only persist in the constant presence of these pressures. I could be wrong, but I think (and I'm recalling from memory, here) that there's experimental evidence to that effect.
Also, this has more to do with bacterial infections than it has to do with viral infections.
