XP-PRO with all the updates. In my startup config there is an entry for <blank>.exe. That is, the file is called .exe with no leading filename. The corresponding Registry entry in... HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run ... looks like this... Name = (Default), Type = REG_SZ, Data = .exe In... C:\Documents and Settings\Administrator ...there is a file called .exe with a size of zero bytes. On deleting either the startup entry or the actual file both recreate themselves. I have scanned with ADAWARE, SPYBOT and AVAST all report no problems. A Google of this condition produces conflicting opinions, some saying it's a trojan others that it's a normal condition in some instances. I'm not having any problems due to this. The start of this condition seemed to correspond to the installation of True Image 10. Is this a creation of TI10 ?
