How can I remove/delete a detected, severe level Trojan file that MSE detected following a full scan? MSE simply stated "Allowed" in the action column. My browser is Mozilla Firefox, v. 3.6.13 and my O/S is Windows 7. Every time I turn on my computer I receive a warning from a program entitled, "System Tool," that says there are 38 infections. Microsoft says this is a fake program that is attempting to sell me an anti-virus application. The name of the Trojan file is: Rogue:Win32/Winwebsec This is listed in the history portion of MSE along with other paths of adware and virus items (the latter have been "Removed" by MSE; but the Rogue:Win32/Winwebsec just says "Allowed" in the action column. Many thanks for any recommendations.

Please answer all of the following diagnostic questions by number in your next reply (no need to quote this post): 1. When (approx. date) did you install Microsoft Security Essentials (MSE) and was the computer fully-patched at Windows Update at the time? 2. What anti-virus application was installed before you installed MSE, was your subscription still current, and did you uninstall it before you installed MSE? 3. Has a(nother) Norton application or a McAfee application ever been installed on the computer? 4. Did a Norton free-trial or a McAfee free-trial come preinstalled on the computer when you bought it? (Doesn't matter if you never used or Activated it.)
