There is an IBM Technote # 1424193 on the preloader which is what is causing this to appear.
Unfortunately it does not say how to resolve it. I have added the files it says to exclude to my virus protection and if it solves it will report back. It did it. See new post from 12/16.
Haven't seen it for a while, but since moving one laptop to 852 I get it all the time.
Anyone figure out which file this is about?
Forum message here.
This technote was no help as the files it seeks are not in the system32 directory.
