I lost a document ODF

Hi everyone ( sorry for my english but I’m french and I’m only 14 so… please, be cool ! ).
Yesterday I downloaded MalwareBites ( Anti Malware ) to clean my computer, it destroyeds a lot of programms, documents… After, everything seems like it was ok. But today, when I wanted to open a file I didn’t find it ! I’ve lost 6 files and they were in the same folder ! I searched in the recycle bin and they weren’t here. So I ask you where or how could I get back my documents… Please ! It’s really important to me…
Thank y’all xx

PS : Oh ! And I’ve got a Toshiba computer with Windows 8 and the 3.5 version of Libre Office.

@Lisa122 - I am afraid it is very difficult or even impossible to find these files. It depends on how MalwareBites works. You need to study MalwareBites and search in the internet for possible ways to identify ways to find your files. This forum is for LibO only. However, if there is a member in this forum who knows MalwareBites you might get a hint.

In general I recommend you to back-up your data and system files regularly (daily, weekly, monthly) and especially before you install or apply a SW, which you did not use before. 1-4 TB Harddisk should in Europe be around 100 - 150 EUR a piece.
