A port scanner is a piece of software designed to search a network host for open ports.
You could run: ShieldsUp to SEE IF you have open ports:
I have the system suite 8 professional program which includes a firewall, virus protection, and spyware protection. Here is the situation. On the bottom right of my screen it says that there has been some suspicious activity that has been caught and has been put in a log. I double click on the flashing fire wall icon and it brings me to a securtiy log. It tells me the time security type severity direction protocol local ip remote host and the application involved also the count. Now this port scan has been happening at very random times but usually when it does occur they occur in very close intervals. System suite says that its a portscan of a major severity inbound from a udp protocol. the local ip is 192.168.0.115 and the remote host is 192.168.0.1 The application involved is either SYSTEM or C:\WINDOWS\system32\svchost.exe For the past about 20 times it has involved the system application. The times it has been happening are today at 5:52 5:56 6:01 6:58 6:59 7:01 7:02 7:03 7:04 and 7:05
I can backtrace it and it says the ip address of the remote host and it says that the host name is unknown. When i click on whois it says [whois.arin.net] orgname: internet assigned numbers authority orgid: IANA and the rest is city state and location of i dont know what.
I have a general understanding of computer but im not exactly sure what a port scan is other than that it figures out what ports are open.
My question is this any threat to my computer or do i have nothing to worry about. Thanks.
