1) yes, but I deactivated it and it's still slow.
2) no.
3) no.

Captain Obvious has some stupid questions:

1) Do you have an "automatic update" feature in your program such
that once per week/month/etc. it reaches out to Internet location
looking for a new version of itself? This can really hang an
application.

2) Does your application in any way use the Internet or network?
I'm asking because many such applications either have to refresh
certificates or they keep a DNS cache. (Firefox is notorious for
this.) The DNS cache has to be flushed and refreshed after a time
period and/or if the host IP address changes . . . A laptop
connecting to a different wifi router can cause the IP address to
change.

3) Do you run Norton, McAfee, or other third party virus
protection. 
That whole "we check every file to keep you safe" promise they
make is a bit of a Clinton Truth. On a full scan they check them
for sure. If you download and run an executable for the first
time they check them, yes. 
The Clinton Truth comes in the second through N-th time it is
run. 
Results of the file scan get cached. File size, timestamps, name,
path, etc. all gets put into a database with either an expiration
date or a current timestamp (sometimes both). Most of these
programs limit the size of this cache otherwise it would consume
much of your disk due to people downloading, running something
once, and deleting. The entries could never go away unless they
are flushed on full scan or expiration. 
When your executable no longer has an entry in this cache it is a
first time run. The size of your executable matters little. It's
the terabytes of DLLs your application utilizes that really kill
you here, because each of them have to be scanned before you can
run.

You can confirm #3 easily. Set up a fresh Windows install,
disabling Microsoft Malware and antivirus and don't install any
other protection. 
Run your executable. First through N-th time should load at
roughly the same speed.
