Troubles began with an infection by the Online Games Password Stealer and SysVenfaKU. I could not remove them because they kept repropagating out, so I deleted partition and reinstalled XP and fully updated from Windows Update. I updated bios by flashing.
Windows boots, but I am seeing a cmd.exe window open on bootup and don't know where it's coming from. It should not be there at all. And the dos prompt in this window looks odd. I get a blinking cursor followed by a period (to the right). The period cannot be deleted.
This reminds me of a symptom of a very old virus, maybe the NIMDA virus that was hitting IIS servers.
Does this ring a bell with anyone?
Can anyone explain the odd dos prompt cusror/period?
