I am using Windows 98 OS with McAfee Virus Scan and Firewall 6.0. I also have a D-Link hardware firewall/wireless router.
If a remote access trojan (for example something like BO2K) is installed on my pc and subsequently attempts to open a port:
1. How might the trojan program get past the software firewall?
2. Assuming the trojan is able to get past the software firewall and open an IP port, would a hardware firewall still keep a hacker from "calling in" and making a connection to the trojan?
3. Assuming my pc is infected by a RAT, does the hardware firewall still protect my pc from a random port scan by any computer on the web?
