windows quick virus scan

[Sam Overdorf]

I have asked this before.
why does erlang cause random quick virus scans on my windows 10?

Thanks,
Sam

It doesn't, so you'll have to provide more information -

* How are you running Erlang?
* What evidence of "virus scans" is there? Do you have event log entries?
* Can you enable ProcMon and filter by the Erlang executable to see
everything it's doing?

Sometimes it takes 1.5 Min to start up using "erl" or "escript" (which
is very annoying).
I can see microsoft scanning by using "taskmgr".
After it finishes the quick scan then erlang startsup and seems to
work just fine.
I like erlang and would like to figure out what my problem is.

Thanks,
Sam

Hi Sam,

What version of Erlang are you using? Older versions started up slowly
on Windows due to a bug - https://github.com/erlang/otp/issues/4193

If you completely disable virus scanning on your machine, is the issue resolved?

I use Windows to do Erlang development and do not experience these
issues, even with anti-virus software running.

Thanks -

I always use the latest version currently 24.3.3.
I use Microsoft Defender for virus protection.
I don't want to disable it because it checks for viruses.
Thanks,
Sam

I'm not suggesting that you *permanently* disable MS Defender, just do
so to test that it is in fact the problem.

If you determine it to be the issue you should be able to exclude the
Erlang installation directory from scanning.

I'll try that.
