According to Springthorpe, “CRAs- Chlorine Realeasing Agents, also possess virucidal activity”. HOCl is an effective
virucidal when fogging a confined space. Park et al describes how  “Exposing virus-contaminated carriers of ceramic tile (porous) and stainless steel (nonporous) to 20 to 200 ppm of HOCl solution resulted in ≥99.9% (≥3 log 10) reductions of both infectivity and RNA titers of tested viruses within 10 min of exposure time. HOCl fogged in a confined space reduced the infectivity and RNA titers of NV, murine NV, and MS2 on these carriers by at least 99.9% (3 log 10 ), regardless of carrier location and orientation. We conclude that HOCl solution as a liquid or fog is likely to be effective in disinfecting common settings to reduce NV exposures and thereby control virus spread via fomites”.

Hypochlorous acid indiscreetly targets bacteria by chemically linking (or attaching) chlorine atoms to  nucleotide bases that disrupt the function of bacterial DNA, impede metabolic pathways in which cells use enzymes to oxidize nutrients, and release energy, and other membrane-associated activities.

As a sporicide, HOCl causes the spore coat to detach from the cortex, where further degradation occurs.
