Hello,
there's a chance that the site you are trying to restore is actually infected, but that could be a false positive since the restoration script creates a lot of temporary files.
To be 100% sure, you should temporary exclude your site folder from the antivirus and complete the extraction. Then manually perform a scan of your website. If you still have a warning, you should take a look at the file and check if it's actually a suspicious one or just a false positive.
