If you know the location of the offending file on your hard drive you can submit it. The easiest way is GetSusp: https://community.mcafee.com/groups/getsusp30-beta-feedback it's a public group which you can join and then download the tool.
In the tool you'll see an 'Upload Tool' option.
It's not uncommon for some things to get by major antivirus applications as variations change all the time and new threats come out by the thousands daily of course.
I believe that Windows Defender gets this one. Try it or any of the other tools I've listed further down the page here: https://community.mcafee.com/docs/DOC-2168
Thank you very much Ex_Brit!
I'll try this tomorrow and then I'll comment results in here.
Thanks again for your help!
OK, good luck.
So, the person with this infection got to submit the file(s) via GetSusp.
I think WinDefender didnt help, but, after finding some info about this one, on another post in here, seems deleting temp files, etc., via Disk Cleanup (Win Sys Tools) checking everything, finally got the job done.
Any news I'll post here.
Thanks for the help Peter.
Run Malwarebytes if all else fails. Make sure it's the free version and update it first.
According to other threads VirusScan is supposed to catch this one, so this is rather strange.
