Windows Defender found something bad on my pc and got rid of it.
After restarting my pc, all of my libreoffice documents had mysteriously changed to "ODT.CDYUUQG" files, and are now either unopenable, or, when opened, contain only a line or two of gibberish, like: "µ*›Ò¯¹�ÏiÖ[-ã�ù¿m¤D Þ¼]". I mean, that's now the whole of the document!
What on earth happened and how can I [easily!] fix it / restore my documents to their 'normal state' ? (Please explain step by step like you're talking to a four year old, without jargon or acronyms--thank you.)
