I used the trial mode example to enter a username and password to change the expiracy to some date way out in the future, and a client Running Trend Micro Internet Security, gets it blockced saying...
It is blocked for doing a Program Library Injection.
Is there anyway to prevent that error
What version of SWF Studio are you seeing this with?
3.4 build 222
Some trickery is required to virtualize the Flash player but most A/V software that I've tried doesn't complain. Do you see the same thing with the latest version of SWF Studio (3.5 build 314) and all the latest updates to your A/V software?
