Issue: Browsers Tend to Crash Each Time an Exploit Is Delivering the Payload to the System...

I am testing a lot of Flash exploits for variouse versions of Flash on Virtual Machines with Windows 7. Id say that 90% of the exploits I tested (on the correct version and correct browser) made the browser crash before the payload could be triggered.

I mainly used IE with versions 8 and 11 and Windows 7 (64bit).

Anyone having an idea or comment about this?

Like... settings... or... I dont know :/
