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.

There are either too many possible answers, or good answers would be too long for this format. Please add details to narrow the answer set or to isolate an issue that can be answered in a few paragraphs.If this question can be reworded to fit the rules in the help center, please edit the question.

Personally I would avoid flash altogether as it's pretty annoying for users. Why not use a static image? – DisgruntledGoat Jan 14 '14 at 16:13
Please answer on topic, as if going your lane, plain text is better than static image... ;) – CamSpy Jan 16 '14 at 8:11

Researchers at the University of California released a paper about how to detect malware in Flash files.
