My understanding is that System Restore does not always play nice with low-level programs, including image save-restores. Also it triggers false positive anti-virus stuff. So to me the only issue is whether to get rid of it completely or leave it at minimum size.
I'd also like to know more about that, as I've never heard about the AV before. And I use Acronis religiously and have never had a problem with it, and I keep system restore around because I don't want to have to restore the whole partition whenever I have a problem; I like to go back to the last checkpoint and see if it works.
