export file is blocked by Chrome – marked as harmful and hacked

Hi,
I just installed the plugin through WP and tried to export my settings from the Customizer.
But Chrome blocked the download. They say the file is harmful and if I try to get the file anyway the tell me that the site was hacked and that I should get the file later…
?????
I installed WP yesterday through Siteground, everything fine, and I’m using the theme neve.
Haven’t tried to download the file through another browser because I feel not save to do so.
Any suggestions?
Is it true that there is something hacked or is it just Chrome with over-control?
Thanks for help!
