After renewing and hoping that the bugs in NIS2013 were being resolved, I an disappointed to say they have not been. I have just a failure of NIS when it need most, and “due to internal failure” I could not risk using this program any further. Given the numerous troublesome posts on this forum NIS is a huge disappointment/ failure, especially for Window 8 users, I being one of them. Failure to scan, failure to self/auto fix, failure to open up selection menus, just failure and internal errors. I have NO confidence in this product after having had Norton /Symantec for many years, nor will I have any compulsion to use in the future. The green tick of positive protection appears to be a lack luster attempt of feigning “safe PC”. BE AWARE it isn’t.
