windows defender issues? & other AV issues?

As I've (seriously) joked previously in my bug 21604 report that has
been referenced already in this thread:
Since Windows Defender is fairly unlikely to be the oh-so-sneaky culprit
when similar issues show up running the LC 9 Script Editor on the Mac
platform, :D therefore it's highly doubtful that this is strictly an AV
industry issue. Viewing it as such could even delay a permanent cure.
Fortunately, disabling Windows Defender's real-time virus options is a
great fix for the symptoms. And like a good cold medicine, that is a
huge relief! Currently I'm using a third-party AV (with some of its
options tweaks as well) so in Windows Defender Security Center, "Virus &
threat protection" is overridden by the other product. But "Firewall &
network protection" and "App and browser control" and "Device security"
are still fully enabled. It's NOT a good idea to disable the whole
shebang, especially firewall. Be sure to have some form of AV installed.
(I also had bad results with McAfee, which is what came pre-installed
with my computer.)
As I've also predicted previously in that bug report, it's a
better-than-average bet that the LC 9 Script Editor is not using the
best practices in some areas, because merely typing usually does not
cause problems in most other apps on a fully Windows-Defended system,
not to mention Macs. Per common sense and best coding practices, the
actions taken by the IDE while we are merely typing and selecting text
ideally should not open the doors to get AntiVirus products involved
continually. Actions that may get vetted by AV, or that may use greater
system resources, need to be considered carefully in terms of approach,
timing, and responsiveness.
Thus, easing the symptoms (quick relief!) may be different than a
permanent cure (no more of this trouble, plus improved performance as a
bonus). The cure would probably make the SE snappier for all users, even
those who never had problems. It would also head off any possible future
issues in case other Operating Systems decide to imitate some of the
Defender type features. It wouldn't be the first time one OS followed
the lead of another.
It's important not to conflate two very different problems that have
been discussed relating to Windows Defender. One is getting the
"jitters" and having trouble typing, copy/pasting, etc in the LC 9
Script Editor. The IDE itself is affected, and presumably may be the
cause. This is the problem that I predict is fairly likely to be more of
a code design issue than an AV issue.
The other problem is apps and their files being flagged or completely
blocked by AV, which is a different and more common problem in the
software world, and very much an AV and file trust issue.
