Hey Eddy:
Will do as you advise, but would appreciate some additional info on three follow up questions:

  1. What does “move to chest” actually do? I could not find anything in AVAST help to explain that.

  2. Will moving WINNT-located files to the chest - or deleting them - crash my system since they are in the WINNT-related files?

  3. In your message, you said
    Also post a HijackThis log here and let us have a look at it.

What is a HijackThislog?

Many thanks again Eddy - your help is mucho appreciated.

Rick
