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
Note that not all files, folders, and registry keys and entries are installed on your computer during this malware's/spyware's/grayware's execution. This may be due to incomplete installation or other operating system conditions. If you do not find the same files/folders/registry information, please proceed to the next step.
Step 3
Restart in Safe Mode
Step 4
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_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- Lcudsgjlb = %Application Data%\Syfwfpwux\Lcudsgjlb.exe
- Lcudsgjlb = %Application Data%\Syfwfpwux\Lcudsgjlb.exe
Step 5
Search and delete this file
- %User Temp%\Logrpaqfriixribkill$.bat
- {Drive Letter:}\RECOVERY FILES.txt
- {Encrypted Directory:}\RECOVERY FILES.txt
Step 6
Search and delete these folders
- %Application Data%\Syfwfpwux
Step 7
Restart in normal mode and scan your computer with your Trend Micro product for files detected as Ransom.MSIL.TARGETCOMP.THHBBBB. 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. Please check this Knowledge Base page for more information.
Step 8
Restore this file from backup only Microsoft-related files will be restored. If this malware/grayware also deleted files related to programs that are not from Microsoft, please reinstall those programs on you computer again.
