Sounds like you had a major crisis and good for you to have on hand meds right
now. Amoxicillin can help in a range of issues and is good to have on hand.
AdenoVirus is, like the name implies, a viral based illness, here's what Chevita
recommends for it:

"Young Bird Sickness
Young bird disease has spread rapidly around the world in recent years, causing severe losses among young birds.
Pathogen:
This is a mixed infection, involving viruses and bacteria (especially E.coli and cocci, but also protozoa).
The pathogens are transmitted by air, dust and contact between birds, as well as via communal drinking water and feed.
Outbreaks of the disease are promoted by stress factors such as weaning, the introduction of strange birds into a loft, vaccination, heat (accelerated bacterial growth, water shortage), training of juveniles (basketing) and young pigeon flights.
Symptoms of the disease:
The disease can take two forms:
Sudden death not preceded by any perceptible signs of illness:
A typical scenario sees young pigeons released from the loft for their daily training (on a hot summer's day, perhaps), whereupon they fly around for an hour and then return to the loft. They land on the roof or on the alighting ledge, do not respond to the breeder's attempts to entice them into the loft, and die within the space of a few hours.
Death preceded by visible signs of illness:
During the period between the onset of symptoms and death (lasting from 3 days to 1 week), the following symptoms are observed: lack of activity, puffed-up plumage, refusal of feed, swelling of the crop, weight loss, greenish-yellow faeces in puddles, vomiting.
Recognition of the disease:
Owing to the numerous pathogens involved in this disease, it is only possible to make a tentative diagnosis.
Similar conditions:
E.coli infection, hexamitiasis.
Treatment:
There is no vaccine against young pigeon disease that could be used to prevent infection. However, sick pigeons can be treated with adenosan. And timely use of adenosan may also prevent an outbreak of the disease in birds suspected of infection. "
And the product:
"adenosan contains ingredients derived from various plants belonging to the Crucifer family, together with immunoglobulins.
Use in young pigeons after races as a metaphylactic measure against Young Bird Sickness:
The plant-based components possess a broad spectrum of activity against bacteria, viruses and fungi. The immunoglobulins enhance immunity within the gut itself, thereby protecting the intestinal mucosa against pathogen attack."
You can get a secondary infection alongside a virus and need an antibiotic,
and the alternate diagnosis includes bacterial and parasitical causes.
The adenosan appears to be an alternative healing modality with a broad range of microbial activity. There wouldn't be any 'rebound' effect from using it, which is good.
Thomas Drugs carries a very broad range of antibiotics that are purchased inexpensively here:
