Photos deleted without permission

AVG has deleted all of my photos and videos after doing a "clean junk" scan through the antivirus app. I did not authorise this and have been using this function for years and this has never been an issue before. It contains over 5 years of memories with family members. Please can you advise how I can recover this data.
