I wanted to start a separate topic on this since I think it is important to know/understand.
Here is post from other thread:

Avast & System Restore:
https://www.youtube.com/watch?v=A9yArbiAHHY&index=22&list=PL68E25CB16ECF9FFASelf Defense Module (SDM):
https://www.youtube.com/watch?v=J5q1ITsTOuU&index=13&list=PL68E25CB16ECF9FFASo, over the years when I have used System Restore I have never been able to have Avast stable after this effort.
After a restore I always had to re-install Avast.
I did not realize about the SDM and what affect it had on System Restore.
This thread is to try to determine what it does....I'm still not sure.
I tried experiment this weekend on PC (Win 7 64bit) PC......
1) Avast SDM enabled.
2) System Restore function creates restore points fine.
3) Restore to those points works fine but Avast seems corrupted......need for clean un/re-install
4) Tried Restore with Avast SDM disabled and same result.....but I'm guessing having SDM off reduces chances of
other issues.
5) Turned SDM off, created restore point, did system restore with SDM off and restore worked and Avast seems to work fine.
So it seems SDM needs to be off for System Restore not to affect Avast's ability to create & restore ?
Also, I assume SDM off may avoid other nasty problems in a System Restore.
My concern would be if you have to go to a system restore in a emergency situation can you even get to Avast SDM ?
I guess having to re-install Avast on a System Restore is not worst thing but my concern would be if this corrupts something and the restore does not work.......in other words I think Avast should work cleanly in creating and restoring via Windows.
Also, like I'm guessing most users System Restore takes restore points at various intervals (eg. login, MS Updates, scheduler, etc.)....which for many of those "creations" the user will not have chance to go into Avast and turn off SDM.
So, wanted to post for other comments and see if others have tested and what their experience has been ?
I think System Restore is pretty important feature and when you need it then it is too late to find out there is issues.
