I just can’t believe the protectionism and fanboyism here. Your post is too off-topic. Jesus christ, this is frustrating. In general this forum seems to run in a certain way: Avast doesn’t answer, and loyal fans drives the OP insane.

ALL, READ THIS POST CAREFULLY: an anomaly how the File System Shield works with the “Scan when writing → scan files with default extensions” default setting

Though I think that it’s a moot point since nobody either does not read it, or doesn’t understand it at all. This is really uncanny. Usually people (end users & product team) are interested about possible faults in the product. I’m reporting bugs/etc. with lots of programs/services and this is easily the most “not caring” community that I’ve EVER seen during these ~15 years that I’ve been doing this (for the benefit of me, and others).

EDIT: Ok, Noel, thanks for notifying.
