'Protection Updates Are Not Valid'????
Just found this in my 360 Security History, it happen 4 days ago and I never knew tell today, and I've NEVER seen this before so can you please help: What does this mean?:
Product Name: Norton 360
N360 Security History
'Norton 360 Auto-Protect cannot load because your virus protection updates are not valid. Please use LiveUpdate to download and install new virus protection updates.'
Why did this happen? Should I be concerned? How can I prevent this from happening again? Thank you all again
