Virus on my phone, how can I get rid of it?

I have just noticed that all my pictures and videos on my SD card were no longer open. Since many of these images are important to me, I have my phone connected directly to my laptop, since my SD card schonmal deleted all images. This time it looked very different: I found a lot of files that were never there before, when I connected my phone. All files are written in weird Greek characters: ╓ $ "Rl¬. Á ~ (copied) . On the internal memory of my mobile phone everything is fine? All the orders and pictures that were before in normal letters are now rewritten in this font Files are all read-only, which is why I can't delete them. For the properties, this file was created on 09.12.1911 22:41 and was changed on 24.01.1908 22:05, which is obviously not possible.Another file was created in 2025 and changed in 1925. I have never had experience with anything like this but for my untrained eye it looks like a virus. I hope someone can help me because these pictures are very important and personal to me.

I hope someone can help me, thanks in advance: /

Connect mobile phone to PC. Download Kaspersky internet security or total security as a torrent. Scan your computer and mobile phone. Then reset your phone to factory settings and re-download everything.
