Avast 4.8 update (manual/auto) failed!

Avast Free Antivirus / Premium Security
21

Just seems really odd that even though I have Avast set up for my proxy server and to use NTLM authentication (and I have a good domain\user and password setup) I am seeing this in the log:

11.04.2008 02:15:30 internet: SYNCER: Proxy enter01:8080
11.04.2008 02:15:30 internet: SYNCER: Type: standard HTTP proxy (rfc2616,2617)
11.04.2008 02:15:30 internet: SYNCER: Auth: no authentication
11.04.2008 02:15:30 internet: SYNCER: Proxy l/p: enterprocity\administrator/***

Also, when I sniff using Wireshark the HTTP GET results in a 407 (proxy requires authentication).

Kind of looks to me like the connection is being made using no authentication

Greetings!

After updating the program up to version 4.8 I have received the same problem. Version 4.7 works normally.
For the Internet I use MS ISA Proxy with authorization.

Excuse for my English :slight_smile:

Interesting results…

As a lst ditch effort last night I rebooted my firewall server and no joy… still had the problem…

To try to determine if this was a firewall issue (even though all the sniffing I was doing did not indicate it was) I did this:

  1. Changed my NIC default gateway to use a gateway address that bypasses the ISA firewall. I have a secondary egress router that routs around things for a few devices that I have that I can’t get to go through the ISA server (IE: Playstation, TiVO, etc…)
  2. Disabled the ISA firewall client.
  3. Ran a connection test and is PASSED!

OK, so then I started to think this was my firewall all of a sudden. I was able to run an update and get Avast to update all it files. I then rebooted.

I figured that if I had to do this once in a while I could live with it. I put my setting back tot he way they were and just for a heck of it I ran another test. It FAILED! :frowning: I went to bed feeling beat…

This morning I woke up and checked the windows event log before coming into work. It updated on its own at roughly 6am this morning!

I am going to run a few more tests when I get home today but so far this looks promising.

i’m having this problem too. trying to update at office behind ms isa proxy and it failed. before updating to 4.8 it’s update just fine.

edit: sorry… my connection just sucks :cry:

25

I’m too :wink:

After checking + modify ZoneAlarm settings with no avail, I tried to uninstall it and install Comodo Firewall Pro (free edition).
Then I tried to check Avast update manually… with SUCCESS ;D

I still don’t know why Avast could not update with ZoneAlarm installed and behind proxy (I already deleted all the programs on ZA program lists except some windows services that were not recommended to be deleted by ZA).
It could be the Windows services that were not deleted from the ZA program lists but it could be something else.

But, I am glad that I can check update behind proxy again 8)

The same problem.
It doesn’t depend on type of proxy or firewall.
It doesn’t depend on type of authentication.
Agree with rcassick

Wireshark confirms that.

28

What’s new with this problem?
when avast 4.8 will correctly complate authentication ?

Beta version build 1178 still had bug in NTLM authentication, but is fixed in latest beta build 1187.

Since you probably cannot update program, here is link for english setup:
avast! Home
http://public.avast.com/~forejt/1187/setupeng.exe
avast! Professional
http://public.avast.com/~forejt/1187/setupengpro.exe

Uninstall previous version, restart and install this beta version. Then in proxy settings for updates fill proxy server address and port, and set NTLM authentication.

If you’ll need setup for another language, just let me know.

Thanks a lot! It works!

I will try it latter today when I get back home.
