Ok, heres what my trojaned computer is being used for.

Disclaimer, I would take something like this seriously, and delete it at first knowledge. My parents are hardheaded and stupid when it comes to the internet and anything PC realated. Ex. mother thinks I'm hacking when I open a dos prompt and type netstat. . Oh well, its not my computer, therefore I cant MAKE them backup there files so I can format this POS and start over from scratch. However, this will make you all say WTF, and maybe even open their eyes as to the seriousness of this.

Remote impacts.
-A proxy for portscans to other systems.
-A password cracker (only reason I say this is because my page file usage and CPU usage is VERY high, could be wrong)
-A web proxy
-FTP server ( I have yet to find the directories)
-People are telnetting in and out.
-Been sending massive amounts of SYN, ACK, and ICMP packets to 3 different hosts, most likely a DDOS.
-SMB requests going all over the internet.
-sending messenger popups

and thats just what I've figured so far.

Local impacts.
-They've deleted local files including Norton AV, AOL (cant blame them), Fport, my installation of Nmap, My firewall (reinstalled in vain), etc.
-They're connecting to my fathers buisiness use only computer on our home network. I believe it uses a VPN to connect to the corporate network. You get the point.
-My mother uses THIS computer to log into a certain universitys FTP and web servers.
-Trojan has a keylogger

I know this is bad, and needs to be remidied ASAP, but I would be on the street if I went against their word on this one.

Oh well, I think I have a big I told you so coming.
