Yeah for me MBam didn't pick it up until like 3 minutes in and this is a relatively new OS (i just fucking reinstalled windows)
Currently doing a secondary scan to see if the trojan.downloader picked anything up before it went down, but it didn't catch anything the first time so I'm thinking maybe false positive.
If NOD32 doesnt pick anything up try running MBam if you have it so we can see if it's a false positive
If it does turn out to be a likely false positive, I'm still leaving it uninstalled until I can get around to maybe doing a false positive report to MBam (although I now don't have the quarantined files)
