Recently I updated both of my systems to the latest Avast client version, 7.0.1426. Both systems already had the free software installed and I used in the in client upgrade button. My XP system has had no issues, however my Windows7 system was first rendered non-bootable and is now unresponsive durings scans and then BSOD.
After the initial version update of the program, Avast notified me that a reboot was required, so I rebooted. System would hang after entering password and would never load. I was able to boot into safe mode, but not safe mode w/networking. This strikes me as odd. In safe mode I was able to run the removal tool from Avast. After removing the software my system was again bootable and ran fine. I then did a cleaninstall of the latest version 7.0.1426 and my system again would hang after reboot after entering password. Safe mode wipe again. After which I went and found the previous version 7.0.1407 and installed it. There were no issues after this install and reboot that I could see. I decided to setup a full scan as I had setup in my previous versions. Ran the scan and after 68% my system began to not respond. Task monitor didn’t even show system being taxed. I waited this out and was able to kill the scan.
Overnight I decided to start the scan and let it run all night to see if it would actually finish. When I got up today my system had rebooted itself and upon login I received a BSOD. So, something from the latest release has caused serious failures on this Windows7 laptop.
BSOD:

Any other security software installed, have you removed the factory installed AV eg ( Norton, TrendMicro etc ) and run the correct removal tool to delet remnants.
It also looks like you haven’t updated your service pack to SP1, not that this should affect it though but you should always apply all windows updates.
No other AV software installed. I don’t recall there being any factory installed AV when I got this years ago from Dell. If there was, then I removed it as I see no traces of any other AV on the system. Removal of Avast was done using their provided removal tool.
Sure I could update my OS, but as you noted that will probably not change anything. It also complicates it when people want to know if anything else has changed recently. Considering this baseline functioned perfectly before the latest version 7.0.1426 I would rather keep it as is in case they need something specific.
I’m mostly posting here as I saw another user with almost identical issues posting a topic. If more people post then perhaps it will get more eyes from Avast. I can function without running my weekly scan for a bit, though I’d prefer not too.
Igor,
Two dump files should be there now, though it is hard to confirm since visibility in the folder looks to be blocked.
Filenames:
031212-14508-01.dmp - first dump appears to be middle of the night while scan was running.
031212-14476-01.dmp - second dump which was on subsequent boot and login.
I just had the same issue…I was on the 7 version and saw there was an upgrade today (I think to 7.2) and following the update laptop stopped at the password…I could enter it and would get the welcome message but it would just sit on that page…after rebooting into safe mode with networking and unistalling Avast I was again able to get into my laptop.
@neksko, your crashes are not caused by avast, it seems like hw fault (memory, cpu); would you mind check memory status (memtest86.com), check cpu temp, etc. Thanks.
I have also had issues with my laptop using Windows 7 operating system after updating Avast to version 7.0.1426 in which the system will hang when I first connect using my DAIL-UP connection as well as when I first login into the operating system or at times when I reboot. It seems the computer will have periods of time when it slows down significantly at which time web pages in some case have difficulty completely loading which requires many attempts to accomplish a complete load of pages in many cases.
None of these kinds of things were occurring prior to installing Avast 7.0.1426 from Avast version 6 which was working just fine. What happens all the time now when I am NOT connected are requests to connect for Avast programs i.e. vl.ff.avast.com, sv.ff.avast.com etc at which time when I do try and connect the DIAL-UP the operating system will sometimes lock up for some time. I now have a 5 minute delay on Avast updates to avoid to much traffic while initially connecting my DIAL-UP which doesn’t seem to make any difference.
Thank you for checking the dump files. I will gladly run a few series of mem-tests, though I am extremely skeptical of that being the actual problem. I say this because the system is functioning perfectly fine running all other applications except version 7 of Avast. I am of the opinion that avast was causing some sort of system event when trying to scan certain file types and this is why the crash is registering a system type event in the dump.
I will update when I find any further information.
We are having the same issue as stated above. We have a large client base that we suggest the use of avast to and this morning we have had over 20 individual sites that have had all of their PCs unable to load because of this update.
Updating to version 7 of the software either manually or automatically causes windows 7 (x64) to hang after having logged in at the ‘waiting’ page.
It has a simliar effect on vista but it hangs pre-login at the ‘configuring’ page.
At the moment we are downgrading to a ‘Safe’ version 6, but this is not something that we can do in the longterm.
I don’t know if this is where I’m suppose to post but I am having the same problems exactly after installing Avast 7 and I UNINSTALLED my McAfee and other security programs it’s a mess and it takes all kinds of messing with start up f8 options and then I have to ctrl alt delete and go to task manager to get on computer and my Avast is turned off can’t turn on dialog box says File System Sheild provider not found what is all this about
After booting the system and logging into windows, the system freezed up and nothing more happened. I had to to a cold boot. I tried several times - same behavior. Sometimes the systems freezed when clicking on the userpicture, sometimes it freezed after enterig the password. But i was never able to see the Icons on the desktop.
Cleaning in safe mode and reinstalling. Now everything works again.
But there is something wrong with 7.0.1426 .
Hi
I have been having trouble, cannot download big fish game manager, or games. computer goes into savemode. etc.
I did ring tech support and I do not know what they did but the computer does not run as before. they wanted to charge me $180.00 to fix problem. When I said I had already paid $180.00 late last year and was covered until later this year, they kept insisting on me paying. when I finally said no i want the computer fixed under the payment I already did they put me onto someone else and who knows what they deleted. Not happy in the least with AVAST this time round.
Well, I haven’t had much luck still with Avast since the update. My system is taking forever to respond while scanning DLL and SYS files and is often bluescreening during these file scans.
Is there some change with deep scanning of these types of files?
Quick Scan seems to function decently.
Something has changed in the latest updates with how Avast is scanning certain file types, as this was not happening previously on full scans.
My laptop still shows no issues with any hardware or other software. As I have seen no fix in the making still I decided to do some tests. I am now using Avast 6 and running a custom scan to scan all memory and files on my system. I have come to find that at 68% my system begins to stop responding, this happens to be while scanning the windows\assembly folder. I excluded this folder from the scan and begun again after a reboot. From here I started watching system resources much more closely and came to a startling discovery. Avast is eating up immense amounts of memory when it scans running processes on my laptop. Once it is done scanning those running processes it DOES NOT release the memory, even if you stop the scan. This is most likely what is causing the slowness which users are seeing.
Is Avast causing these running processes to eat up memory? It looks like several basic windows processes begin to use up more then double their normal amount of memory when it scans them:
dwm.exe
wltray.exe
bcmwltry.exe
explorer.exe
svchost.exe
delldock.exe
I know there was a previous issue with Avast and some Dell drivers. Who has the ability to test this out and confirm?
I’ve had three laptops lock up this week after upgrading to 7. Boot to safemode, uninstall Avast and computer boots correctly. Will be uninstalling Avast from all corporate computers on Monday.
I just purchased Avast last week for the first time ever. Since then, my Outlook Email will not function properly. It locks up after one use and I have to re-boot my computer just to make it do anything. I am currently not even able to open Outlook. I have re-installed my Office program but it still isn’t working. Has anyone else had this problem?? My laptop seems to be working ok otherwise.
… like most other folks, I’ve also had the same frustrating problem after installing the latest Avast 7.xx upgrade. And also, like other folks, it seems a total uninstall in Safe Mode is the only way to get over this issue. The problem I have now is that my machine is now vulnerable.
Avast people: the product seems to have a flaw - not everyone in this forum can be wrong, particularly with the diagnosis and the workaround (i.e. uninstall Avast). Any chance on some positive commentary on your product? :-\
