Avast NG / Secure Virtual Machines renders Windows System Protection useless

[Lisandro]

Hi Lisandro,

I think it would be helpful to the Avast folks if listed the specific version of Avast.  Looks like there may be a combination of rlease candidate and gold versions being used in this discussion thread.

Yes, thanks.
I'm with 2015.10.2.2214 (the latest).

The specifications and subsequent system check for NG are too darn low - if it will try to install the NG function on my totally underpowered win7 netbook.

Acer Aspire One, Win7 Starter (32bit) 10.1", 1024X600 screen, 2GB DDR3 RAM, Intel Atom N255 (1.5GHz dual core) CPU and 250GB HDD.

I actually though that it wouldn't install on my crazily under powered netbook - then I saw it trying to get up and running with my netbook on its digital knees.

Ok, I've been reading this thread and, the more I read, the more confused I get. I'm using Avast Free 2015.10.2.2214. My C: drive recently started using 10.962GB Shadow Copy Space, apparently because of a bug in Avast and has been rapidly filling up my drive (128GB Samsung 840 Pro). I also have system Restore turned off (it never worked correctly in Win and I found imaging with Macrium Reflect to be far superior). What can I do to stop this hemorrhaging into Shadow Copy?

This latest update has block chkdsk from starting and removed all earlier system restore marks on my two different computers. I uncheck the VM action and all works ok now. But does that weaken paid Avast Internet Security less effective? I see lots of comments on this, but no  definitive answers from Avast.
What's wrong?
