Recommending a filemon and regmon are both good ideas what result did they come up with
u could also try using trillian as a irc client to see if it is a problem with his version of mirc also install a winsock tracer on mirc and see what results that gives get a good but very obscure firewall and get it to ask weather to allow each connection get rid of msn client and use trillian if u want use msn get ur friend to access the internet while he has a fake ip eg 192.168.0.1 that way nobody can connect to him if he is running a trojan get a good trojan scanner get an intrusion detection system the P+P exploit u are refering to is the Universal plug and Play bufferoverflow not all versions of windows are affected look up this exploit to find out what version are affected win95 & win98 by default is not affected though can be by installing the Universal plug and Play system L8r Amoediun Ps Hit Me >I lurk alot here and I know a fair amount about computer security >although I still thought I would hit you with this question. > >I have a friend on mirc that is being "penetrated" in someway.
