Trojan.Agent

OK, just downloaded the text file from the Malware Bytes forum, at the post referenced above by JRViego (thanks for that!).
If that is indeed your post, the contents of the read me are:

If you still have MalwareImmunizer on your system, I recommend you disable all immunity prior to running any scans with any other scanner.
I'm thinking it's far more likely you don't have this software still installed, or at least active, and if that is the case, you can simply delete that folder.
Recommend you restore the folder views to default after you have done this.

MalwareImmunizer is one I have tried, long ago. Is of somewhat questionable and limited value, since it will only cover a tiny percentage of the malware around, and I don't know if it's ability to block that percentage has been tested in a meaningful way. It claims to work by loading these harmless txt files in a folder with known malware names as the title, so as to fool any attempt by a trojan to install itself that it is already installed, when of course, it is not. Terry, the developer, was based in Singapore. Seems a nice enough guy, and well motivated, but lacked the resource required to develop this idea. Perhaps that's as well; it was pretty much doomed to fail.

Bottom line, you're clean.

 

Yes, that was me.

 

Okay here is the file. I think I had the program you are talking about, but removed it later on...

 

I did a search on Malware Immunizer. I did not find it. Also I looked under Add/Remove programs, and it is not there.

 

Someone, sometime, has had Malware Immunizer installed on that computer.
Since you have on the 'pooter a txt file with that in the title, your search didn't work.
(Unless you already deleted that folder?)

Search in hidden and system needs to be enabled.
Let us know if you find any more of those read-me's.
I doubt there'd be many more, or MBAM and maybe NOD would have nutted off more during scans.

 

The show updates box was ticked, I think by default. I didn't realize there was such a box until you told me. Thank you for all the help folks. I really appreciate it!

 

More than welcome.
