Since the 13th of March I have been geting trojans detected by Norton AV 2004's auto protect. The trojans seem to arrive at random intervals and vary. The first one was W32.Welchia.B.Worm. Then 6 trojan droppers over the next two days. Backdoor.SDBot.Gen. W32.Randex.AR. Then Bloodhound detected two unknown threats. Then a couple of IRC Trojans and BAT.Trojans.
Sounds to me like someone is determined to get in my system or some program on my machine is downloading trojans. I've looked thoroughly at running processes and cant see anything unusual. Startup areas seem fine too. I have Sygate Personal Firewall enabled and presently the Sygate.com portscan on my machine shows i have stealthed all ports except UPnP(intentional for MSN messenger Aud/Video). Another open port is the telnet port that my router modem stupidly leaves open even when WAN side telnet server is disabled. I have changed the port number of the telnet server in the router settings for security.
Im running XP Pro SP1a.
How on earth could they be getting in?
