Blue Screen on Boot with Avast Mar 19
« on: March 20, 2015, 11:55:14 PM »
I've used and trusted Avast Free for more than 5 years and recommended it to many friends and colleagues (as I am a networking professional), so I was extremely disappointed when I found my computer, last night, Mar 19, in an endless blue screen crash on reboot loop after in-program-updating (by answering an alert) .  I attempted uninstalling Avast using Safe Mode and reinstalling from the website, but I still faced the crash loop thereafter.  I had to go into safe mode to uninstall Avast and install Avira to resolve the issue. 

According to Alikhan, Avast Beta is stable, but I'm not going to try it right now.  Boot BSOD loops are too serious for me and it really hurts me to know I installed Avast on my sister's XP computer this week, and if she updates it, she may face the crash loop too.  I'm done with Avast for at least a few months (until the next main release).  I hope you guys work it out because I find Avast Free to be an efficient, professional and full-featured experience with a nice interface.

Could you please confirm your avast version? V9 or V10?

There has been issues of the program updater corrupting installs for a few users on the normal stable release. A clean install fixes the issue.

I mentioned the BETA is stable but it's pointless to use if you are not affected by any of the issues you have.

Did you do a clean avast! install after the BSOD?

Regarding the BSOD, I'm sure avast will want to analyze the memory dump. Any chances you could upload it for them?

Alikhan, In response to your post: I apologize: I was using the version number from the properties Avast installer I downloaded today from Avast.com.  The file properties probably weren't updated.  I don't know what version they're handing out right now, because it doesn't say on the download page, and I wouldn't unless I installed it again (which I don't want to do), so I simply updated the post with the date of download rather than presumed version number.

The first install was from the program (I have kept it up to date for over 4 years).  Now, as I said, the first thing I did was uninstall Avast in safe mode, and do a clean install with a fresh download file from avast.com, but it resulted in the same boot crash loop.  And as for the memory dump, it's a 2GB file, and I didn't let the screen complete the lengthy process of dumping it and using up 2GB on my hard drive (nor do I even want to know how long that would take to upload).  As I said, I don't want to fix this or install it again.  I've switched to Avira because of this at least until there is another official Avast release.  At that point, if it happens again, I will probably attempt a registry clean of Avast entries too.  I don't want to risk this happening to my or my friends' computers again.  I just want to alert the developers of this issue.

The problem is you are the only one that has reported the issue.

It's important to establish if you were updating from v9 > v10 or just from v10 to another SP of v10.

2014-10-21 was the release date of avast 10.

Did you do a clean install after the BSOD to see if the issue persisted since there was a chance of a corrupt install?

Alikhan,

It was probably an update from a newer version (I update it whenever I'm prompted to).  And, yes, I uninstalled and reinstalled and had the same issue.  It may also be helpful to note it doesn't crash directly after install (I could use the Avast interface and even do a quick scan without issue) ... The issue only happens after boot.  Windows boots almost fully and a few of my tray icons would appear, but the blue screen occurs before the Avast icon appears in the tray.  Maybe others haven't reported the issue because they aren't using Windows XP SP3 (as I am).  I can't risk my computer becoming unusable (especially from software designed to protect it).

Well, that explains it a bit more.

Avast works fine with XP SP3. The only thing I would suggest if you want to re-try avast! is a clean install. This normally fixes nearly all issues that are not known. It is most likely a corrupt install that happened. Here are a few thread examples, though they are not related to your BSOD, they all occured after a program update.

https://forum.avast.com/index.php?topic=168013.msg1194676#msg1194676

If you try the clean install and it does not fix your issue:

It's either an issue with avast
Another software is conflicting with avast
Your PC may be infected with malware

I could also get attention to this thread from a malware analyst to see if there are any issues with the system if you are willing to.

Perform a clean install:

Note: It's important you used the stub online installer from the one I linked.. NOT the offline one.

Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn't)

1.Download your version of avast! and the avastclear tool:

Avast Free Antivirus
Avast Pro Antivirus
Avast Internet Security
Avast Premier

Download Avast Clear Tool

2. Uninstall Avast by control panel  [If you don't have Avast in control Panel go to #3]
3. Uninstall in safe mode using Avastclear. [Running Avastclear is normal mode will give a prompt to go into Safe Mode]
Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle.. if so, uninstall it and reboot.
5. Install the version you downloaded.
6. Reboot.

Free: If you have the Free version, register the product for free for a year from the avast! UI.
Paid: If you have a paid license, insert the license key/activation code after the reboot at stage 6.

If you have any questions, please don't hesitate to ask. It's better to ask than make a mistake and start over again with the process.

Alikhan,

Thanks for informing me of Avast Clear.. that may be helpful when I'm willing to try again.  It makes sense that after using Avast for more than 4 years, it could become corrupt to the point where it prevents me from booting, but it's still disappointing.  For now, I'm going to stick with Avira at least until the next official Avast release to give the dev team time to fix potentially un-yet-discovered issues.

That was my point for the memory dump. I recommend using the avast cleanup tool every major release (e.g from v9 to v10 etc)

Could you report your issue on this tool : http://public.avast.com/supp/util/avastsupportR2.exe

No need to install anything. This goes directly to the devs of avast! so they can analyze the issue.

It's hard to find issues without the dumps.

Well, that's all that can be done for now until you re-try avast. The new beta should be released in less than a week I would assume.
