[CURRENT ISSUE] Anti-Virus blocking User Folder (Screenshots/Gallery/Mods..)

hi --thank you for replying--i need administration rights to add an application?  i''m new to the pc and windows.  i was playing the sims 4 and used custom content (something new to me) and then suddenly origin or windows needed an update.  ever since then my computer was considered by an ea agent as crashing.  when the sims travelled on a date the computer screen would freeze up and it would say:  The Sims 4 (Not Responding).  so the tech suggested i  dump my custom content and try to uninstall and then reinstall origin and the sims.  so i began playing the game again, until i came to the gallery area and opened up ''my library'.  i noticed that i had red xs on some of the households i created.  i think it's because i  dumped the custom content out of my game and also because i reinstalled a new version of the game without the custom content--is that right?  also i was wondering if my sims 4 was saving the game to one drive (the cloud).  the ea tech told me that the sims was not supposed to run or save from one drive and that it would be saved to origin.  if i download custom content is it saved through one drive?  this is what i was wondering about as to how the game would connect to one drive.  in other words, is saving my game and or using custom content using one drive by default ????--i hope i'm makinging myself clear.---thank you
