here is a side project I've just launched which might come in handy for certain situations.

It's a very simple and free "do one thing and do it well" online service with exactly one feature: you upload a file, and it tells you — based on a ClamAV check — if that file contains a virus or not.

I'm not having any ambitious plans with this project, but thanks to very low operational costs, I thought I can as well put it out there and keep it alive — maybe it's even useful for some people every now and then (just today, one of my coworkers forwarded me a fishy-looking email with an attachment, and using virusaas.com turned out to be the least painful way to do this kind of one-off check for a virus).

I've also released the source code of the web app under GPLv3 at https://github.com/hygieia-saas/hygieia-webapp, although it's not as polished as it could be (no tests, for example — but see above, no ambitious plans).

The main reason to do the project was to follow through with my own tutorial at https://manuel.kiessling.net/2021/05/02/tutorial-react-singl..., which worked out quite nicely.
