HowTo: Repair Registry after Virus Attack

One of the most frustrating things about being infected by a virus is they mess with your registry so much, there wasn’t much you can recognize from what remains in your PC even after you totally exterminate the virus either using antivirus or manually.

And on top of it, antivirus company seems reluctant to really clean up the damage, at least without extra money to buy an extra functionality from their software.

This is a collection of registry fix I compiled from most of Indonesian made virus since brontok to amburadul.

This registry fix can repair virus symptoms such as

  • · Disabled task manager
  • · Disabled regedit
  • · Virus hook to explorer, safemode, and winlogon
  • · Missing or disabled options regarding file extension, hidden files, and super hidden
  • · Internet explorer caption
  • · No run
  • · No find
  • · No control panel
  • · And some more

Some of the entry I put in the repair file was credited to an Indonesian antivirus website I fond long-long time ago… I forgot the URL. Some was taken from a friend of mine which in turn take it from his friend mine which in turn take it from his friend… I simply don’t know who I should give credit to. I also created some of the entry.

Download Repair.inf here

To use the file simply right click and install it

Note:

Please be sure that there is no active virus in your computer when executing repair.inf. You can do this by using an antivirus or manually using process explorer tools such as ProcessXP from Sysinternals.

Some entry mark with “Your Product ID“,”Your Product Name“,”Your Organization“, and “Your Registered Owner” are meant to be change according to each person preference.

In some case, the virus registers an inf file with other file, for example a jpg file. In this case, the install option doesn’t appear when you right click on the file. If this happen, pray that run or command prompt not blocked.

If it’s not blocked, download repair.inf, put it somewhere on your hard disk, for example put it in your C: drive. Then just run “rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 C:\repair.inf” command either from command prompt or run menu.

If it’s blocked, you’re screwed… :(

  2. Your repair.inf unblocked my task manager. Control panel is still not showing up from Start > Settings. Start + E is still blocked (cant use short cut to open explorer and my time (bottom right) has VIRUS ALERT! apended to it.

    Thanks for your help anyway, I’m one step closer to cleansing my pc.

    I didn’t get time to reply sooner.. sorry :p

    First

    First of all, check your Regional and Language Option (run intl.cpl). In either Regional Option (XP) or Format (Vista) tag, customize, try to change the time AM and PM symbol back to normal.

    If you succeeded, restart your computer to really see the changes were successful. If it does, then all left for you to deal with is the control panel problem.

    Otherwise, continue to the next step

    Second

    (Please bear in mind that the following section may cause your OS to crash, and you should backup all important data prior to following this section. It would also help to have your OS installer ready. I really hope you’re not using HP)

    Most of my problem with (most likely fake) virus warning in tray icon have something to do with malicious dll hooked to explorer, which make cleansing far more complicated since explorer is executed every time (and the dll might be hooked to other application as well)

    The first thing you should do (assuming you’re certain there’s no active virus running in memory) is to search for suspicious dll attached to explorer using tools such as Autoruns

    (Please take a look at HowTo: Manually Remove a Virus from Computer)

    Look into explorer, services or winlogon tag within Autoruns for entries without description, publisher, or both (excluding entry with File not found. Test the entries by unchecking it then refresh (F5) the view. Legitimate dll should still be unchecked after you refresh, while malicious one will overwrite your changes almost instantly and the entry will be checked after you refresh.

    If you do find a suspicious one, use you have a couple of way’s to deal with it, but i suggest you use Unlocker (see the link above). Go to the dll’s path, right click, and unlock. You’ll see which application the dll is hooked into.

    After you unlocking it, you have the choice either to simply delete it or to rename it (in case you want a souvenir :p)

    Go back to Autoruns and test again by unchecking and refresh

    If the entry doesn’t seem suspicious after you uncheck it, reboot you PC to see if VIRUS ALERT! still appended to time (after you go through step like first section)

    I hope by this time the alert problem is gone (one problem off your hair :) )

    If it’s not, things get really complicated since those kind of alert can be caused by a malicious driver that have a tendencies to damage windows if you mess with it.

    Third

    The last thing is missing control panel

    I recommend you go through this site which have helpful hints about registry

    Hide Control Panel, Printer and Network Settings

    Disable Control Panel

    And Control Panel

  5. I was told it was easy to change things in the registry. I really didn’t understand it could crash and possible totally ruin the operating system. Long story short, I had to reinstall windows because of what I did. Now, I don’t touch the registry anymore and just use one of the many windows registry repair programs out there.

  6. It is a mess being screwed up by a virus. Many times you will have to re-install Windows to wipe every single error out and it is a pain in your butt.

  7. Hi,

    My laptop was infexted by xp police antivirus. I have tried to remove the malwre by running antimalware. the program founds savral torjan virus which it fixed. After restarting the system, now the issue is its not showing any desktop icon or start menu or even quick launch.

    I have tried all the option of booting in safe mode, using previous best known configuration but the issue is still the same. Even it playes the windows starting sound.

    Your help will be highly appericiated.

    Thanks,

    Nick

    • Hi Nick

      It seems that your antimalware program leave some broken line in your registry
      I recommend u to seek prof help

      If you want to do it yourself (at your own risk), Ill try to help you out…
      Mind though you’ll be searching needles in a haystack

      The needles leave clue though, so if your carefull enough you’ll find it

      But first you have to somehow open explorer or command prompt

      Since task bar and desktop icon gone (which indicate something preventing the main explorer to open),
      does ctrl-alt-del work?

  9. When I tried to log on to ours dekstop, a box saying “there are not sufficient resources to load” my account with the default something-or-other came up. The box had a timer that was going to close the message, and then when it closed it would not log me on. I could not turn it off normally so I cut the power. When I turned it back on I logged on fine?
    I read here PC Repair but couldnt make sense?

    • seems like what would happen if you run out of HD/RAM space… did you leave your PC on for some time before you tried to log? if its already on when tried to log, perhaps theres a process that eating all of your memory running in the background… anti virus scan or a virus can cause something like that… you might also want to check your C (assuming youre running windows), you should have at least 200 MB if you don’t want windows to start acting weird… :p
