Step 5

Restore these modified registry values

[ Learn More ]

Important:Editing the Windows Registry incorrectly can lead to irreversible system malfunction. Please do this only if you know how to or you can seek your system administrator's help. You may also check out this Microsoft article first before modifying your computer's registry.

  • In HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\DMusic
    • From: ImagePath = "system32\DRIVERS\JM.sys"
      To: ImagePath = ""{random values}""

Step 6

Search and delete these components

[ Learn More ]
There may be some components that are hidden. Please make sure you check the Search Hidden Files and Folders checkbox in the "More advanced options" option to include all hidden files and folders in the search result.
  • %System%\DRIVERS\JM.sys
  • %Program Files%\Internet Explorer\12~~.tmp
  • %Program Files%\Internet Explorer\6357.jpg

Step 7

Restart in normal mode and scan your computer with your Trend Micro product for files detected as TROJ_AVKILL.SM. 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.
