After updating to this new version of Avast, my Macrium Reflect Free won’t do a scheduled backup. I get a 0x1f6 error message. I can’t get any help from Macrium because I’m using their free home version. Any help would be appreciated.
Here is something about it > http://forum.macrium.com/Topic10311.aspx
To troubleshoot, disable the shields one at a time in avast and check each time if Macrium is working.
I suggest to start with the behavior shield.
Yes, agree with Eddy. I have Macrium free as well, but no issues. However, I did not upgrade to the new version, I completely wiped Avast from my systems first (Safe Mode), then used their tool as a secondary check for removal (Safe Mode) and then rebooted to a normal system. Installed the latest and no issues.
FYI, I had massive issues when installing over an older version; network issues, Firefox, CCleaner, Thunderbird, Steam, etc. Safest bet, do the above and be happy.
Same here.
I disabled all shields and Macrium Reflect still won’t run.
Avast is a nice program but this is a deal breaker for me. I cannot use Avast until this bug is squashed.
I tried uninstalling Avast as suggested, re-starting the computer and then re-installing Avast. Still same issue. I can manually do my backups, but can’t run the scheduled backups.
Did you do as I suggested in reply#1 (disabling the shields one at a time and check) ?
That was the first thing that I tried and when that didn’t work, I did the uninstall and re-install that was suggested and that didn’t work either. So, I’m stuck doing my backups manually until there’s a fix for this bug.
Which version of Windows ???
Also have the same problem with the latest version of Avast (17.1.2286) stopping Macrium’s (Paid version) scheduled backups. Manual backups still work.
After doing a clean install of Avast the problem still persisted. I thankfully had a copy of Avast offline (12.3.2279+2280), so have reverted to that until the problem is sorted.
I’m using Windows 10. If you go back to a previous version, it always comes up that you’re in danger using an out of dated version on Avast. I sure hope they do something quickly. It’s not very comforting having to rely on doing the backups manually.
No need to do backups manually. This should help you solve the problem:

Yes, this works in Windows 10. It’s what I use weekly.
But we are talking about Macrium …
I answered a users question. 
So, as of now, there’s no solution to this issue. Macrium just sent out a notice of an upcoming upgrade. Waiting to see if by chance their new version will correct this issue or is we’ll have to wait for Avast to correct it.
It would not surprise me if they work together to solve it.
I am having the same problem with Macrium Reflect error 0x1f6 on daily backup.
Avast seems to not let the task run. Someone suggested turning off avast self-protection
might help, but I do not really know enough about it. Also uninstalling Avast will do it.
I would be good if someone from the Dev team would acknowledge the bug and perhaps give an ETA for a fix.
The avast self defense has nothing to do with this.
Huh?! Are you trying to tell me the Avast Development Team have nothing to do with fixing bugs caused by their AV? :o
I responded to Galt and I never said that the development team has nothing to do with the problem.
