Can you request Google to re-scan your website via Search Console per https://support.google.com/webmasters/answer/168328 ?

That website is not  mine,and I am not sure whether it is malicious or not .But I am confused about the behavior .Since both address point to the same site(points to same ip address,the address www.keepvid.com redirects to address keepvid.com),if google consider the site as malicious then warning should be shown on both case,or both address should be shown as safe.but in this case one address is shown as safe and other as malicious.So isn't it easy for a real malicious site to take advantage of this behavior ? 

Thank you for providing more feedback. Adding requester "msrchandra@chromium.org" for another review and adding "Needs-Review" label for tracking.

Thanks for reporting the issue. This is working as intended in Chromium since the corresponding sites are marked as-such in the blacklists. Nothing for Chromium to do here.
