Norton deleting perfectly good files

hi guys,

every so often norton seems to wake up and decide it doesnt like certain files on my PC, especially files ive had for months, in a folder i have previously blocked from with Norton. i find i have to go into the control panel and 'restore' the file.

 

getting very annoying because these are perfectly safe files that i have created myself. i have so many folders 'blocked' from within Norton that its just not funny.
