I would like to take a third party ad - flash banner on my site, I can place it as an iframe (to show a page with the banner, hosted on other domain), or I can host it myself.
I have seen, when browsing other sites, that sometimes my antivirus/anti malware software blocks the ads for being harmful...
I know that flash is quite shady thing as it is possible to use it for things of a dark side.
Is there a good way of checking if flash banner has vulnerabilities, security holes or ways for the owner of it to target visitors of a site and spread malware or harm their computers?
As I understand, if there is a 'hole' in it, the bad guy under control can target visitors just on a specific time, or for specific browsers, platforms, OS'es, mobiles, countries, etc.
