The virus "TR/Agent.P.2" displays a window with a License Agreement (EULA). If this is not validated, the programs stops its execution:

The trojan generates a mutex named "UNIQUENAMEHERE".

It calls an URL and receives delievered data, which then creates the following files:
pdata
ddata
lddata

TR/Agent.P.2 opens TCP Port 6666 and generates a ICMP request to all IP adresses im the range 213.203.209.118 - 213.203.209.126.

It also creates a WOHIS query to the following servers and asks for the domain names in the file "ddata ":

"whois.internic.com"
"whois.adamsnames.tc"
"whois.nic.be"
"whois.nic-se.se"
"whois.nic.cc"
"whois.nic.nu"
"whois.nic.dk"
"whois.nic.nl"
"whois.partnergate.de"
"whois.nic.it"
"whois.nic.li"
"whois.nic.ch"
"whois.nic.at"
"whois.crsnic.net"
"whois.publicinterestregistry.net"
"whois.nic.uk"
"whois.afilias.info"
"whois.nic.biz"
"whois.neulevel.biz"
"whois1.verisign-grs.net"
"whois.dns.pl"
"whois.nic.us"
"whois.ripe.net"
"whois.nic.ag"
"whois.cnnic.net.cn"
"whois.denic.de"

The file "fkd8df6s.lnk" is a link, which the trojan calls with a parameter:
"C:\WINDOWS\system\k.exe /uninstall"

The trojan removes all the created files and copies itself in the Windows directory with the name "removeme.exe".
