I get pop ups fom my virus scanner stating "Fin scan detected "
Anyone know what a fin scan is?..Thanks in advance
"TCP FIN Scan
Hackers use the TCP FIN scan to identify listening TCP port numbers based on how the target device reacts to a transaction close request for a TCP port (even though no connection may exist before these close requests are made). This type of scan can get through basic firewalls and boundary routers that filter on incoming TCP packets with the Finish (FIN) and ACK flag combination. The TCP packets used in this scan include only the TCP FIN flag setting.
If the target device's TCP port is closed, the target device sends a TCP RST packet in reply. If the target device's TCP port is open, the target device discards the FIN and sends no reply. Figure 4 shows the TCP flags field when the FIN scan is used."

You might want to install a good firewall too, viruses and hacks are different things and while its good to have a virus scanner, you need to take better care protecting your privacy.
