My recent items folder suddenly get emptied - why ?

[puffin7]

All read documents are happily retireved from the task bar in RECENT DOCUMENTS but maybe once a week the RECENT ITEMS folder is emptied (not by ME). As far as I am aware I have all the right settings otherwise items wouldn't be in that folder. How can I stop this happening?

Hi and welcome to SevenForums,
Some security program may clear items after running a full scan
What do you use and any other third party utility like ccleaner..... ?
