Yes.
And there is lots of information on “emupdate” (emergency updater) if you use the Forum “Search” function
Edit:
For example: http://forum.avast.com/index.php?topic=140730.0
msconfig is the inbuilt tool comes with windows.
it is safe, in case you are an advanced user.
He was asking about the ENTRY “emupdate” in msconfig. 
You’re not going to get any legitimate answers about this from the avast team or from Schmidthouse. They’ll just tell you to either blindly trust avast or go away. Funny that someone with all this in his signature will tell you to either blindly trust software or not use it:

Pro>FF26(WOT)>NS2.6.8] OpenVPNBut I guess he is in the habit of going to websites and installing software he doesn’t trust. It’s also interesting that he talks about not confusing kindness for weakness. When I apologized in an attempt to be civil because I though maybe I overreacted, he took that as a sign of weakness and started criticizing me to another member. He still has not had the courage to address me directly however. Yet here he is, still trying to look important by giving the same nonanswer I called him out on before.

Do not Confuse Kindness for Weakness
BTW: After well over 10 years I have given up on avast! It is not the same antivirus it used to be that just simply did it’s job, and you could get helpful advice on the forum on the rare occasions you did have a problem. So I have taken the advice of wonderful people like S–thouse, and -Dimlight. Thanks!!!
He asked, I gave my opinion.
Or are only you entitled to an opinion.
The component is part of the Antivirus you chose to trust.
If you don’t trust it, don’t use it. 
A nonanswer isn’t an opinion.
lololol
Say you ;D
I think people would be helped out more if you gave useful advice rather than giving worthless “opinions” anyway.
It never ceases to amaze me when a person’s intelligence fails them, they have to resort to personal attacks.
If you have no useful advice of your own to contribute, then why waste your time with worthless personal attacks
I’m just saying. ;D ;D
ANXINTEMPO07,
Schmidthouse’s opinion is probably correct as far as it being safe. But you’ll have a hard time getting an answer as to whether it’s necessary to permanently be in your start-up programs, or whether you can/should remove it, why some people have it and others don’t, etc. Instead we’re just told we should trust it and not be concerned what avast! does on our systems.
ok, ques is clear now.
if you trust avast then you sud allow this one too.
I don’t know. Why don’t you tell me why you just chose to attack me rather than answer questions on the other thread?

How did all this attack solve anything about what the OP was asking
Boy unbelievable :-\
How did your attack on my intelligence on this thread or the other one solve anything?
Can you be any more hypocritical?

With due respect guys, this thread is no longer helping anyone (particularly the OP) and should be closed.
To the OP’s question…
The Emergency Update is installed as a Scheduled Task, and runs on boot, and at other designated times (see the schedule in the task properties).
