A routine Flash Scan following a definition update revealed what may be a false positive for "Trojan.Slugin". The file is "caller64.exe" which is part of the Samsung ML-2850 Series printer software. The questionable file was at: C:\Windows\Samsung\PanelMgr\caller64.exe Other instances of the (same?) file are at: C:\Program Files (x86)\Samsung\Samsung ML-2850 Series\Install\Application\SPANEL\PanelMgr\Caller64.exe C:\Program Files (x86)\Samsung\Samsung ML-2850 Series\Install\Application\SPANEL\SPanel\Caller64.exe C:\Program Files (x86)\Samsung\Samsung ML-2850 Series\SPanel\caller64.exe I submitted the first file above (the one identified as "Trojan.Slugin") to VirusTotal, and MBAM was the only product to find anything wrong, identifying it as "Trojan.Slugin".
