If you have been using the computer since this last MBA-M it really is pretty much a worthless post, plus it was run two days BEFORE the HJT log you posted. In order to really clean a computer the steps must be done as rapidly as possible. We have no way of knowing what else may have gotten on the computer in the past 11 days. I am not sure who you are speaking to when you say
uploaded the requested file to each site
I am not even certain WHO this Grinler person is, he certainly is not a regular poster here.
If you want to clean the computer then you will have to update MBA-M and run another Full Sytem scan and have it clean everything found. You say your Trend Micro is now identifying the file this person requested but you do not say what identification it is giving. Unless I get full information there is no way I can tell you what to attempt to remove it.
