Hi, my current OS is Vista-Home and I use NIS 2009. I was visiting a trusted site this morning when i got a message in a text box saying that I needed to scan my computer because malicious software could have been detected, it opened up "My Computer and started running a scan similiar to Windows Defender. Im not sure how this got through but after closing it out and my browser I checked my history and it says the following; Severity-Info Rule "Default Block UPnP Discovery" Stealthed (###.###.#.#, Port ssdp(####)). Inbound UDP Packet. Is NIS not registering this threat because it usually spams the history 4-5 times every couple of minutes or so, is the firewall blocking this and how do I get rid of this.
I updated Malwarebytes right afterward and NIS 2009 went into safemode and scanned, nothing came up. This is really freaking me out, any help would be greatly appreciated.
