Hi,

I've noticed that the same log in box keeps popping up when I
try and log in to some of my subscribed sites.

Has anyone else have this happen, I must have had the same
one pop up with a set of keys for a logo & it asking for an ID
& password.

Could this be a root kit or Trojan.

Gary,

Download HijackThis.
http://www.bleepingcomputer.com/files/hijackthis.php
http://209.133.47.12/~merijn/files/HijackThis.exe
http://www.downloads.subratam.org/hijackthis.zip

If you are on Windows XP, extract the file. Do not just doubleclick on it! This opens HijackThis in a temporary folder. This would interfere with the possibility to make back-ups.

Unzip to a folder other than your Desktop or the Temp folder. Then, doubleclick HijackThis.exe, and click "Scan".

When the scan is finished, the "Scan" button will change into a "Save Log" button.
Press that and copy and paste its contents in this thread.

Most of what it lists will be harmless or even essential, don't fix anything yet. Someone will be along to tell you what steps to take after you post the contents of the scan results.
