Strange System Restore behavior

The only other thing I can think of to isolate the problem.

1. Completely remove Avast and keep it off until the problem is solved.
2. Install MSE for testing your system. You can always install Avast later.
3. Keep the problem computer from any contact in any fashion (wired or wifi) from your NAS and clouds.
4. Check and make sure your Restore Point is set a 5% and stays there.
5. Make sure nothing is scheduled. No auto update of anything.
6.Scan your system with Eset Online Scan.

I'm not really sure what to do with your Raid setup.
Never used Raid.

Every week it seems that there are more Avast problems reported. They have really fallen in just the few years since they were recommended here almost co-equally with MSE. Today I would class Avast with AVG which was already bloated up and buggy before Win7 was even in beta. For some reason it takes years for the word to filter through, probably because so many still stick with XPired tools and methods, even try to carry them over when they finally migrate to Win7.

I agree. I've used Avast for years and it has saved my hump on numerous occasions but now seems so full of bloat I think I am done. I have a pro license with them until may/15 and when its done I think I am too.

The "Tools" caused the issue on my PC.

I uninstalled Avast Free and then only reinstalled the 3 Basic Shields (nothing else).
It has been behaving itself since.

I think part of the problem with some of these anti virus is they try to do things a anti virus isn't meant for.
They start checking email, tweater, I.M. ebay, Craigs List the coffee pot and my sister stockings. ON and ON until it starts tripping on itself.
They try to take all the user interaction away from the user.

Just be a anti virus program that stops nasties from getting into my system.

I don't want to join a Cloud or have a bunch of shields to select or any other little do dads one can think of to make it look like a better program.

I personally use MSE for a anti virus program. and Marwarebytes Premium. I really don't care how much resources they use because of have lots of resources. I'm not a enterprise person with domains and large networks just a home user.
The reason I use them is because no muss and fuss and for years they have worked.
For years I was buying 2 ,3, 4 different Security Suites a year.
I would look and read reviews and keep changing for what ever they said was the new and greatest one. It was B/S then and I believe still is.

Agreed.

The best protection is to make (multiple) regular backups.
Depending on what your system is used for they may need to be made daily!

I create monthly partition backups on Patch Tuesday (actually Wednesday here) before I install the MS Updates.

I usually also create backups if I'm installer "dodgy" software like drivers, as they are often responsible for "system killing" crashes.
