The default settings is for the malicious 'server' file to inject itself into the target system's Default Browser memory space and then run as a phony 'duplicate' browser process, which enables it to bypass detection by firewalls and routers. The trojan creates a 'server' file on the affected system which alerts the trojan-maker when an affected system is online and which then gives access to, monitoring of, and even complete control of an infected user's system - giving him (among other things) the possibility to steal usernames & passwords, banking or credit card info, or any other private information that may have been stored, typed or viewed on-screen while the computer is infected. Since June of 2006, numerous users have reported experiencing similar issues with their browser which were later found attributable to a malicious trojan - specifically one based on Poison Ivy, an advanced "reverse connection", firewall-bypassing remote administration tool.
