Cannot perform a system restore in windows 10 due to Avast file

[HairyScot]

I just had this problem and retried the restore after disabling aVast's SDM but it made no difference. I got the same error.
I am running Windows 10 Pro X64 with aVast 2016 Premier Version 12.3.2280 (Build 12.3.3154.23).

EDIT: Had to perform a similar disable of MBAM to enable system restore to work.

However, I'd still like to know how to circumvent this problem in a situation where I need to restore a system because of boot failures and so will be unable to change aVast's settings.

Install the OS, drivers, applications that you use etc.
Make changes as you wish (e.g. change background, colors, disable power saving etc)
Create a image of the drive.

Make a daily backup of your data (incremental is the fastest way)

Use that in case of problems.
Works a lot better then a system restore point as a system restore point is very limited and might not solve the problem.
A system restore point can also cripple security (related) software.

@Eddy
I must confess to playing Devil's Advocate on this topic.

I use Acronis TI, so I agree that daily backups are the way to go, although I prefer differential to incremental.
I would add that continuous or non-stop backup is also a good idea if you want to get point of time recoveries or file versions.

However these features come at a price, either financial or in terms of disc space, so lots of people will rely on Windows features like System Restore and/or File History.

As for System Restore crippling security related software; I'd be interested in finding out just how that happens and how, short of not using the feature, it could perhaps be avoided.

System Restore isn't intended to restore your entire system.
It does come in handy on lots of occasions. Some time in the past, there was a problem when using
System Restore and Avast because Avast protects it's own files.

Bob is right. Any antivirus should do this. There is a known way to infected a system using System Restore when you restore an infected restore point. This is a must have security measure.
