Possible risk?

[whirling1]

my norton firewall (internet safety 2002) has popped up with trojan warnings last 2 nightd s running....first was hack 'A' tack , second was sub seven..... message just said An attempt was made to access my pc using these progs...ive got NA2002 running and it detects nothing...also used online scanner and nothing there either.....is it likely that these programmes are on my PC ??? or are these progs used to detect trojans on a pc?

You don't necessarily have the trojans on your machine, it just means someone is trying to connect to the ports that those trojans would use, and if you were infected it would allow them to do.. whatever it is they do.
