1. Would it be possible for a attacker to gain complete control to a computer without the aid of a Trojan?
No firewall and no router
File sharing is disabled
Windows/IE completely updated
2. If it is possible because of a unknown Windows/IE flaw, would a firewall and or router help?
I am having a debate with someone saying it is possible and I say it is not possible.
Even with a Windows flaw, a firewall is integrated with Windows and it will be bypassed.
Any links provided will be greatly appreciated.
