About two weeks ago I noticed a pop-up from my Norton Firewall saying it had blocked the NetBus Trojan. Oh that's good I thought, except now this happens every 30 mins when I am online, there doesn't seem to be any harm done but it's very annoying.
Any ideas why this has started happening, it never happened before?? :?:
Is there anything I can do about it, is it a threat?
I run Mozilla Firefox with Norton Antivirus & Norton Internet Security Firewall
also Spybot, Adaware and spywareblaster frequently.
