Hi,
I have just spent several hours identifying & disinfecting a new trojan which adds an addin into IE. All the virus companies are listing it as low threat, is it far from it, it is a logon/password downloader.
It shows up as req.dat in system32 and the following link may help to get rid of it
http://forums.techguy.org/t351238.htmlPlease note that even though the virus scanners say they have got rid of it, they haven't, it is extremely persistant.
Hope this saves someone a heap of time in the future.
Regards N Mc Donald
