@Mel A malicious, fake Adobe Flash Player update program will be detected by Trend Micro Maximum Security before it's installed on your PC. Per @pragmatic's reply, if you're still concerned, you can directly access Adobe Flash Player official website or the Adobe Flash Player update website https://get.adobe.com/flashplayer/ to install the updates. Thanks and please let us know if your question was answered.
