Firstly, if your website has been hacked there is a likely scenario that it will also get blacklisted meaning various security providers will mark it as dangerous. This scenario is understandably quite bad for your company’s reputation. VirusTotal will come in handy here to quickly check the situation given it aggregates results of over 100 security blacklists and will allow you to track it over time.
As noted, the Google AdWords team will also based on the results here decide if your ads should or should not run. Therefore it is super important to make sure your website does not show up here.
