Title: Avast Update to 5.1.889 "breaks" Windows 7 Home Premium x64
Post by: cardocpdx on January 22, 2011, 02:48:51 AM
I find several threads that all seem to be on this same topic.

I posted earlier today at http://forum.avast.com/index.php?topic=69526.0

Quoted text follows
----------- begin quote ------------
3 week old install of Windows 7 Home Premium x64.  Fully patched.  Windows firewall, Windows defender and no other "security" software.

System will boot but at log on a "userinit.exe error occurs and freezes system.  ALT+CTL+DEL does bring up the screen to start task manager etc.

Since last night I have:
1) Restored from backup 2 days old
2) Installed avast update again
3) System broken - Can't log on.
4) F8 and system Restore (2 day old restore point). Could log on but most applications won't open.
4) Boot to safe mode and uninstall Avast
5) Able to log on, applications work.  Clean install of current download from avast
6) Boot time scan (1 suspicious file deleted from Chrome Cache)
7) System broken - Can't log on.
----------- End quote -----------------

8) booted to safe mode and un-installed Avast.

I've been using Avast for 4 years and have never had an issue.  This however is very flustrating.

Does anyone have and installer for a verson of Avast 5 earlier than 5.1.889 for a x64 system?

Yeah same here. 

@cardocpdx;  FileHippo is a website that carries previous version of Avast!.
Another possible thing to check would be re-install current Avast!, but do not install the Behavior Shield when you do.

I am another user of W7x64 Home Premium who has had no problems with Avast! during the entire beta cycle.  Since you have a new W7x64 installation, how did you get it?  Did you do an upgrade of an existing computer, buy a new computer (perhaps with preinstalled Norton or something else you deleted) or some other way?

Avast has normally been troublefree for me. However, I am having one really weird problem on my laptop with AIS 5.1.889. On the PC it works fine and the computers are virtual copies of each other. The OS's are Windows 7 Home Premium 64-bit, the architecture is AMD, 4GB of memory in both and so forth. Most programs that I use on both are the same.

However, when doing a Complete System Scan on the laptop, it always locks up the computer at about 67% while scanning the "c:\windows\winsxs" folder. No solution yet. Except maybe one, it will complete the scan in Safe Mode, but that's not an ideal solution.   >:(

Have you run a chkdsk to fix file errors just in case?

Once I did a clean install on 7 Pro 64 bit all is now okay.
Other than the server update issue the other day
Did the another computer with Vista 64 bit and just updated the program........... I expected trouble but got none.
And another computer with 7 Ultimate 64 bit just updated the program its okay (I also expected trouble)

Further Info.

My install is a clean install from a Windows 7 retail disk.  Drive was formated by windows installer at time of install.

Drive is clean, no errors with check disk and WD Diagnostics gives it a clean bill of health.  I have recovered (again) from backup and am currently running with Avast version 5.0.677 and updates turned off.

FWIW 3 other computers in the house (1-W7 x64 1-Vista x32 1-Vista x64) are all running fine with latest Avast.

The ONLY things I run that runs as a background process is a Virtual DVD (not daemon tools) and the "connector" for my home server from M$.  Everything else is plain vanilla Win7.  This is my "reliable" machine and I attempt to keep it lean and mean.  The Vista x64 machine is my "play" computer and I expect to have to restore it 3 or 4 times a year.

Same problem with windows 7 64 bit ultimate.
When will avast bring out a stable version?
5.1.889 is rubbish.
It cost me already several days to reinstall a backup. :-\

Not really. It brings quite a lot of improvements.
I'm glad to have participated on the beta phase and I could have all "my" troubles be solved.
It's running smoothly in my computer (not precisely a common one... If it runs in my computer, it could run in quite a lot of others as, generally, I have a complex installation).

Working fine here as already said on the original topic of version 5.1.889.. I also participated in the beta testing and had 0 problems since the 3~4 betas of avast! 5.1.
Never saw a serious issue topic by any avast! evangelist since the release of the stable (last) version..
Now the thing I don't understand is when people have the OS fully updated, patched and when is everything running OK, avast! comes and ruins everything.. kinda strange, hein?

But back on topic, I'll suggest you to install a earlier version of avast! (per example: 5.0.677) and see if you have a similar problem.

Don't know what your "connector" is, but have you tried "disconnecting" it to see if you can login then.  Need to look for what is conflicting with Avast! so the developers can investigate further.  There are millions of Avast! users with W7x64 not broken, which doesn't help your problem.
Another approach is to do a custom Avast! install with only the file shield, and if the problem goes away add in the network and behavior shields (others as necessary) until the problem recurs.  There have still been some problems reported with the behavior shield but haven't seen this one.

The connector is for Windows Home Server (WHS) from M$.  It seems to be mostly a front end for remote desktop.  It queries the server for status on load.  On demand it remotes into the control console on the server.  It is possible that it somehow modifies the parameters used by/passed to userinit.exe.  The connector service also runs on my other W7x64 machine without issue.

The WHS connector service is (aparently) not the culprit.  It was set to NOT autoload during a portion of the time that I was unable to log in (except in safe mode). 

My theory is that Avast is falsely flagging userinit.exe as dangerous and not allowing it to run which kills the log on process.

System file checker says that the file is un-modified since install.  Avast 5.0.667 does not tag my copy of userinit.exe as dangerous.

My other W7x64 machine's copy of userinit is exactly the same size.  I didn't hash them or run a compare so I can't guarantee that they are identical.

Apparently the issue is not as wide spread as I initally thought.  It looks as if my machine and a couple at http://forum.avast.com/index.php?topic=69526.0 are the only ones that are having this issue, and all but mine are running multiple security products and/or have changed brand of AV (potential incomplete un-installs of other products). 

I don't want to leave Avast so my plan is to stay with 5.0.667 for a couple months and then revisit the upgrade situation.

Avast has a KILLER product and I still recommend them highly, which is why I took the trouble to (try and) communicate my problems to assist them in continuing to have the best AV out there.

A quick try at a fix is to go back to .889 but do a custom install and do not install the Behavior Shield, which seems to have caused similar problems on occasion and has had significant changes since the version you are using now.  Please give that a try, since if it works it will help the developers isolate the problem.

I agree with you also.  All my programs except IE8 started crashing after the Avast 5 update. Things have returned to normal now after I uninstalled Avast.  I want to go back to an earlier version also.

I don't have time for further testing right now.  If I get some time I'll try it without the behavior shield.

I had a similar problem except I updated to the newest Avast and everything was still working perfectly. Then Windows Update installed a few critical updates and everything started going haywire. Almost all programs wouldn't run including IE8 and 9 beta, Chrome, Firefox, control panel wouldn't open, etc. I tried system restore many times going back to before the Windows updates and that worked temporarily, but every time I rebooted, the Windows updates reinstalled and everything got screwed up again. I finally did a complete system restore and started reinstalling all software, etc. I got all the Windows updates installed, and everything was working perfectly. Then I installed the latest version of Avast, and I started having all the same problems like before. I uninstalled Avast and installed Microsoft Security Essentials until this problem gets worked out, and everything is running fine now. There is definitely a problem with the new Avast version and the latest Windows security update files from several days ago.

Hi all, new here.

Installed it myself too, Avast free, did not finish the installation process and the laptop froze, I could not do anything (it might be that i did not restart the system when i uninstalled the MSE). I restarted it and it seems fine so far. Win 7 Pro (64bit) action center says that the AV is out of date, but it is not, just updated.
I have the latest version on Avast free.

Same Problem here!

AVAST FREE 5.1.889 killed my Laptop (Windows 7 Professional 64bit), PC (Windows 7 Professional 64bit). My old PC (Windows XP Pro) got no Problem.

Same behavior as above. Programmes didn,t Start, IE, Outlook, MS Office 2007, Total Commander, etc.

All started when i rebooted my Windows after the Update. 5.0.667 did work fine since Months. There is definitly a Problem, maybe its 64bit Version, idk. Can't test it, I have only 64bit Windows 7 PCs around here.

... My theory is that Avast is falsely flagging userinit.exe as dangerous and not allowing it to run which kills the log on process. ...
I tend to agree.  I'm on XP, but when I try to login under one of the user's on my system, I get "userinit.exe: The application failed to properly initialize. 0xc0000022".  It won't continue booting and I don't get desktop icons, taskbar, or start menu.  I went back to 5.0.667 and everything works fine again.  More on my problem here if it helps diagnose yours:

Computering is not an exact science :)

Exactly, sort of :P . Computer platforms are like the weather -- chaos. Which in reality it IS an exact science, but we just don't have the capacity yet to consider every possible variable. ...and that's just because we don't always know what they all are.

Take a combination of variables -- all of which are mathematically sound and of course, follow the laws of physics. But there are SO MANY of these variables at play, that a human mind (and often even a supercomputer) cannot predict what will happen.

In the current state of the PC world, there are simply too many possible combination of hardware, drivers, memory, CPU, video chipsets, network interfaces, applications, services, did I mention drivers? :).

I can easily see how things will break on 1 percent of machines, no matter how tried and tested it is. It even happens when Microsoft updates things.
