I navigated to a particular website to view their online catalog when I received a message from Norton of an attack on my computer. It listed MY computer as the attacking computer, the ATTACKED computer being 46.252.130.200.80 and the attacker URL as being defender-isde.co.cc/scan1b/237/freesystemscan. Norton immediately blocked the intrusion and severed my internet connection. I run Windows 7 with Norton Internet Security Version 18.5.0.125 pre-installed by HP. Everything is set up for Norton to work automatically and provide full time protection. I ran a scan immediately after this occurred, and nothing was detected...?? I don't understand what is going on here.
