I solved with this:
- Load up the task manager and go to "services" tab
- scroll down till you see "IswSvc", click on it and then click the services button on the bottom right
- Scroll down in the new window till you see "ZoneAlarm Toolbar IswSvc" and select it
- Right click and press properties
- In the "Startup type" drop down select "disabled"
- Reboot and verify arma3 game files in steam
- click play, click allow on the ZA pop up and enjoy arma3
Thanks guys for your support!!
