Will acyclovir show up on a drug test?

I can't see how... acyclovir is a modified nucleotide, benzodiazepine has a completely different chemical structure. Also, while I can find papers on false benzodiazepine positives from compounds like sertraline, none of them mention acyclovir. It would be pretty easy to tell the difference between the two in a confirmatory test, even if it did cause an initial false positive on a screening test.
