In general I'd say yes; defer.

But specifically for this error, it will repeat every time (the content
won't change, so Avast will still say "I'm not prepared to deal with
this) - so we'll take temp-errors until the source times out.
This could be regarded as suboptimal, even though not incorrect.

If we can identify the specific problem from the Avast prototcol
I'd suggest a hard-error result would be preferable. But only if.
