When WebScan starts scanning your website it may receive a redirect from the original website it visited.
This is often harmless but there are cases where a website has been compromised and visitors to the website are redirected to a malicious site that is impersonating your website so that it can either try and capture Credit/Debit card information or personal information from your customers.
You should check with your web developers to confirm this is a legitimate redirect. If it is not your web developers should investigate the cause of the redirect.
