Sorry, I didn't mean you would knowingly use Softonic but as it happens, the My Permissions cleaner has links to Softonic so it depends where you got it from. And Clean my Drive could have come from MacPaw, another dodgy supplier.
If you want to download anything other than from Apple, only buy direct from the developer. You can check this out via Google, and where Softonic or MacPaw is involved they can usually be seen in the announcement.
By Apps in Greek, Apple apps are fine, but apps of a Greek origin may not be. Most are fine, I'm sure, but you can often learn from other comments. Before you download anything, feed the name, as it is written, into Google. That will invariably come up with both supplier details and comments from other users.
I see your Pages-out have gone to zero. Excellent.
