I don't have the removal tool but you can probably get it yourself and run it... the trojan has very likely set values in your hosts file which are blocking you from some anti-malware sites. Solution is to remove those entries, ie. reset your hosts file.
You can do this manually or with this tool:
==download HostsXpert from http://www.funkytoad.com/content/view/13/31/
-click Restore MS Hosts File button.
Some security applications, possibly also various malware, will lock your Hosts file [as a protection]. If HostsXpert is unable to restore your file check for applications which may have incidentally locked it. Lock/Unlock hosts exists in Zonealarm and Spybot S&D.
ZoneAlarm : look under firewall, advanced;
Spybot : click Tools, Hosts File, uncheck "Lock Hosts file read-only as protection against hijackers"
Or just...[ but a Spybot setting may over-ride this command....] do this:
Go Start, run, type cmd -press Enter. Paste this line into the window at the prompt, press Enter, close the window and try the Restore button again.
attrib -r -h -s %SystemRoot%\system32\drivers\etc\HOSTS
Manually: the hosts file is at C:\windows\system32\drivers\etc\hosts. Run the command above then drag the hosts file onto a notepad to open it. Delete all extra entries so that your file has only this entry :
127.0.0.1 localhost
Save it, then try the removal tool URL again.
