C:\windows\system\ntinvisible.dll
I have searched this site but cannot find anything about this particular trojan.
first its not a site ...its a file in a directory...
1. make sure that your system displays hidden files and folder...if its not go to Control Panel > Folder Options > View (tab) and click the show hidden files and folders...now try navigating to that file...if you cant delete it...its probably because its in use...so you can either reboot in safe mode and delete it...or just end its process and delete it
2. it could be from anywhere...btw do you mean from a file or more like from a person?
hope this helped ya...peace
