No problem with Windows XP Pro SP3, Avast free 17.8.2318 and Firefox 52.5.0 ESR version.  Unfortunately I can't suggest an answer to your issue.

Another Windows XP user with problems after latest Avast update to 17.8.2318. System works for about 15 minutes, then cannot load new web pages on either Chrome or Firefox, e-mail client can no longer send/receive, system then hangs / freezes and I cannot shut down properly - CTL-ALT-DEL does not work, have to do a forced power down (hold down power button for 10 secs) to reboot.

I tried to use system restore to go back to my previous version of Avast (System restore showed that this morning "Installed Windows XP Wdf01009") - I tried to restore to 2 days ago - system restore Failed.

What is the best method to roll back to a previous version of Avast - and which version do you suggest (I do not know what version I had that was working until today)?

 I tried Add/Remove programs to roll back but that was not an option - I did "repair" the install - but that did not help the problem. I have another XP machine (on the same network) running Avast 17.4.2294 with no problems. I have been using Avast for years - this is the first time I've encountered an update that disabled my computer this badly.

Does Firefox start in Safe Mode (hold down Shift key and then start Firefox)?  Can you try to temporarily disable each Avast "shield" (Settings -> Components) to see which is causing the problem?

Unfortunately, Avast does not offer older versions.   Some websites may offer them, but they may not be genuine and may well install malware instead of Avast.

Does the computer consistently hang after 15 minutes?  What if you boot and then let it run for 15 minutes without doing anything?

My machine running Win10 currently runs free Avast version 17.7.2314 (build 17.7.3660.244 dated 10/3/2017 7:18am). Avast Settings window shows a newer version 17.8.2318 (dated 11/9 5:46am) is available but all attempts to update have failed with Unknown Error. I downloaded the latest version from Avast website and attempts to install failed, as well. Has anyone been able to update to 17.8.2318 on a Win10 machine -- which is up-to-date w.r.t. Windows updates?

Yes, I was able to update last week. Windows 10 64bit (4) units, and (1) 32bit unit.  There is/(was?) a bug in the Self Defense Module, but it should not affect downloading and installing the update.

[REDACTED]

Good to know that some people have been able to update. Since I'm not able to update to the newer version, what do I do next? I worry about remaining vulnerable to all the issues that have been fixed in this new versions -- which I'm not able to avail.

[REDACTED]

Have the updates been postpone? I have 3 computers that need to be updated, two of them have been updated, one of them is still waiting for update. They are all password protected and I don't know the password to force the update.

I didn't have a problem updating.

New version 17.8.2318 (3705.249) works fine on all my Windows 7 (pro and ultimate) and Windows 10 Pro computers.
I have an MSI Netbook with Windows XP Home SP3 and after updating from 17.4.2294 (3482.0) to the new version 17.8.2318
all seemed ok until I can not open or run any programs, a look in the event viewer shows Information Event ID: 7035
"The AswHwid service was successfully sent a start control" they appear about every 3 minutes, then I get an ERROR Event
ID: 7011 "Timeout (3000 milliseconds) waiting for a transaction response from the Avast antivirus service" After the second one of those I loose control of any programs or apps. Completely uninstalled 17.8.2318 and installed 17.7.2314 (3660) and it does the
same thing? Had to recover my Acronis image which had Avast 17.4.2294 (3482.0) and it works OK. Any suggestions?

I was about to uninstall Avast because I have a five-day challenge coming up tomorrow on PrimeGrid, and I really could use that core. I decided to give it one more chance and ran the repair from the Windows control panel. Good thing I did, because AvastSvc.exe is now back to using less than 1% of the CPU. Something must have gotten hung up during the upgrade.

Got a problem? Try this first:

Repair Avast:
Control Panel> Program and Features (Add/remove program)>Select Avast> Select Repair. Reboot when completed
https://www.avast.com/faq.php?article=AVKB204

If Repair doesn't fix the problem, try the following:
Clean Install of Avast:

I've been using Avast for years but have never seen it hang so badly while updating ... something about 'debug' very near the end of the update process stopped everything and, 'This is embarrassing. GUI failed to load', AV service is not available'. Windows Defender, which I don't use, complaining about AV having been turned off.

Tried 'Repair' twice but it didn't work. Uninstalled and re-installed, which seemed to go well enough if a quite slow on Windows 10 64 bit. All is well now, I think.

This is just a guess, but it's possible you got a corrupted aswHwid.sys file which somehow got left behind when you uninstalled.  You could try using avastclear.exe and then checking C:\Windows\system32\drivers to make sure aswHwid.sys is really gone - delete if it isn't.  Then reinstall (again  ) the latest version from scratch.
