I’ve had similar problems with Renoise and Avast.
The latest trick from Avast is that it scans Renoise AudioServerPlugin32 as malmware/virus and deletes it without a question.
This is with the latest version of Renoise (3.1.0.rc2).
I’ve reported this to Avast but it’s not yet updated to virus database.
Also adding exception to Avast rules doesn’t work for some reason…
I think I made a bad decision to go with Avast antivirus…

I had the exact same thing… after updating avast, it didnt kill my audioserverplugin32.exe anymore…
But I did have to reinstall renoise…
I had this similar issue but in reverse order. Whenever I started renoise, Avast Antivirus Shield would crash. This post was helpful in locating the issue and I found a solution here if anybody needs. Basically I had to update my Avast to it’s latest version to prevent Avast shield from crashing.
