Step 1
Before doing any scans, Windows 7, Windows 8, Windows 8.1, and Windows 10 users must disable System Restore to allow full scanning of their computers.
Step 2
Identify and terminate files detected as TrojanSpy.Win32.EMOTET.TIABOFDR
- Windows Task Manager may not display all running processes. In this case, please use a third-party process viewer, preferably Process Explorer, to terminate the malware/grayware/spyware file. You may download the said tool here.
- If the detected file is displayed in either Windows Task Manager or Process Explorer but you cannot delete it, restart your computer in safe mode. To do this, refer to this link for the complete steps.
- If the detected file is not displayed in either Windows Task Manager or Process Explorer, continue doing the next steps.
Step 3
Delete this registry value
Important: Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this step only if you know how or you can ask assistance from your system administrator. Else, check this Microsoft article first before modifying your computer's registry.
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\UPnP Device Host\HTTP Server\VROOTS\/upnphost
- (Default) = "{random characters}"
- In HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\UPnP Device Host\Description\{262DFC30-A9EC-4089-AE41-1DD542D7E10C}\UDN Mappings\uuid:32d0d20f-2613-46a1-add3-5198c3d6a24d
- (Default) = "uuid:262dfc30-a9ec-4089-ae41-1dd542d7e10c"
- In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\footpublish
- DisplayName = "footpublish"
- In HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\footpublish
- Start = "SERVICE_AUTO_START"
Step 4
Search and delete these components
- %Windows%\SysWOW64\footpublish.exe
- %AppDataLocal%\Microsoft\Media Player\CurrentDatabase_372.wmdb
- %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host\upnphost\udhisapi.dll
Step 5
Search and delete these folders
- %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host\upnphost
- %All Users Profile%\Microsoft\Windows\Caches
- %Windows%\ServiceProfiles\NetworkService\AppData\Local\Microsoft
- %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft
- %Windows%\ServiceProfiles\NetworkService\AppData\Local\Microsoft\Windows\Caches
- %Windows%\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host
Step 6
Scan your computer with your Trend Micro product to delete files detected as TrojanSpy.Win32.EMOTET.TIABOFDR. If the detected files have already been cleaned, deleted, or quarantined by your Trend Micro product, no further step is required. You may opt to simply delete the quarantined files.
