Hi DavidR
Removing the protection is in the public domain. In fact Eddy showed me how to do it when I wanted to just scan the System Volume Information. Subsequently I wrote some scripts to deprotect and protect that folder. But as you imply, going any further than that is fraught with danger. However, if Microsoft have the knowhow they really should be passing it on to the Avast programmers. My personal interest in this stems from the fact that the first time I got a virus in the SVI I disabled and enabled System Restore (as is the standard procedure) but my computer failed to boot. I got back on track eventually and the virus has disappeared but the experience has made me nervous. On the only other occasion the standard procedure worked perfectly. But it would be nice if Avast could identify it AND GET RID OF IT!

I believe that avast team are working on that as a possible future enhancement. I think that there was something along these lines in a previous thread.

I have stopped using System Restore it is just not reliable enough, I take regular image back-ups of my HDD and If I get into a fix, it is a few minute task to install the last image.

There are many, many reasons why a System Restore may fail. For example, see "Why are previous restore points not working?" in the "Troubleshooting" section of this official Microsoft page:
http://www.microsoft.com/technet/prodtechnol/winxppro/plan/faqsrwxp.mspx

There's lots more on that page that's worth reading too. Note especially the sections on "Does System Restore protect personal data files?" (the short answer: no); "What should I do if System Restore does not work?"; "Why are my restore points missing or deleted?"; "Why does the System Restore Wizard lockup?"; and so on. Just a few minutes on that page ought to convince just about anyone that System Restore is not intended for heavy-duty system protection!
