Step 4
Restore this modified 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\Windows\CurrentVersion\Explorer\Advanced\Folder\Hidden\SHOWALL
- From: CheckedValue = "2"
To: CheckedValue = ""1""
- From: CheckedValue = "2"
Step 5
Search and delete these files
- %Program Files%\MD.pif
- %User Temp%\dll1.tmp
- %Windows%\fonts\lstis.sys
- %System Root%\AUTORUN.INF
- %System Root%\abc.dll
- %Windows%\Fonts\bet.sys
Step 6
Scan your computer with your Trend Micro product to delete files detected as TROJ_PACKED.DFI. 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 7
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.
- D:\Program Files\Kingsoft\Kingsoft Internet Security 2008\kasbrowsershield.dll
Step 8
