Hi. So I got a virus the other day, I think the vundo one. I used Malwarebytes, Spybot, Superantispyware, eset online scanner, AVG and I think one more to get rid of everything. I've run some of these multiple times afterward and everything seems cleaned out.

But upon doing more research into viruses, I saw a forum entry where they mentioned some registry folders related to a virus and I still have some of those folders remaining. They seem harmless now and my spyware and malware programs haven't identified or deleted them, but I wanted to make sure that 1) my computer really is safe and 2) it's safe to delete these registry folders.

I have 6 of these folders in registry. Each have between 2 and 6 values:
HKEY_CURRENT_USER\Software\h8srt
HKEY_USERS\.DEFAULT\Software\h8srt
HKEY_USERS\S-1-5-18\Software\h8srt
HKEY_USERS\S-1-5-19\Software\h8srt
HKEY_USERS\S-1-5-20\Software\h8srt
HKEY_USERS\S-1-5-21-1993962763-884357618-839522115-1004\Software\h8srt

And I'm running Windows XP, Service Pack 2. Thanks for any help!

Can you post your most recent Malwarebytes log and then update it and run another scan and post that one as well? The registry entries are from a rootkit. I would like to see if it has been removed or if it keeps coming back.

Hello ,they do need to go and that requires Editing the Registry.
Modifying the registry can be dangerous (and can render your system unbootable) so it's advisable that you make a backup of the registry before proceeding.
Modification of the registry can be EXTREMELY dangerous if you do not know exactly what you are doing so follow the steps that are listed below EXACTLY. if you cannot perform some of these steps or if you have ANY questions please ask BEFORE proceeding.

Backing Up Your Registry
  • Go Here and download ERUNT
    (ERUNT (Emergency Recovery Utility NT) is a free program that allows you to keep a complete backup of your registry and restore it when needed.)
  • Install ERUNT by following the prompts
    (use the default install settings but say no to the portion that asks you to add ERUNT to the start-up folder, if you like you can enable this option later)
  • Start ERUNT
    (either by double clicking on the desktop icon or choosing to start the program at the end of the setup)
  • Choose a location for the backup
    (the default location is C:\WINDOWS\ERDNT which is acceptable).
  • Make sure that at least the first two check boxes are ticked
  • Press OK
  • Press YES to create the folder.

For more information about modifying the registry, see this Microsoft article: http://support.microsoft.com/default.aspx/kb/256986


If you are not comfortable doing so. please post in the HJT forum for supervised assiistance.

Would you recommend using ERUNT instead of just backing up my registry with Windows Registry Editor?
And does it seem like there would be any virus remnant other than just those registry folders? All of my malware and anti-virus software come up clean, but those registry folders worry me.
