About a week ago I ran live update on my NIS software on my Windows 7 PC on which I have been using it for years. As is often the case, it required a system restart, so I did it. After the restart my desktop was all messed up. Icons were gone, I couldn't even find them in my desktop folder. My personalized background image was gone. All in all the system was nowhere close to configured how it had been. Fortunately I was able to do a system restore to a point a few weeks prior and while it wasn't perfect, it was close enough that I could make things back to the way they had been without too much effort. Now NIS is again prompting me to do a system restart to complete a live update. Obviously I want to make sure my AV software is up to date so I want to do it, but not if doing so it messes up my system again by doing so. Has anyone seen this and is there a solution ?
