While on lione tonight I suddenly received a message that there was a problem with NIS2012. Having run the auto fix option It said it could not be fixed automatically and directed me to NR&R download to rmove and reinstall my product,which I have done,after it failed to reinstall automatically I was able to reinstall via my account page. I have no idea why this should suddenly have been necessary and my question is does this mean that something on my computer was attacking my NIS2012 and done some damage.? Everything appears to be running ok now and have done a quick scan which found only tracking cookies and am currently running a full system scan to be sure.
