"Intrustion" Prevention error code 0x80010203

Upon computer startup (no internet connection) I get the following error:  Intrustion Prevention failed to load.  Error Code: 0x80010203.  Because there is a typographical error in the message and because the first step in fixing this is to uninstall Norton AntiVirus, I'm skeptical.

 

1. Is this a real Norton AntiVirus error message or some type of malware?

 

2. Is uninstalling and reinstalling really the correct next step?

 

3. Can you fix the typographical error if this is all legit?

 

I tried Ask Nathan and searched through several forums but no one addressed the issue of whether Intrustion is a simple legit typo.

 

Can anyone help?
