I've looked around and found several solutions to getting rid of similar viruses, but not this one. One on Trend Micro said to go under the registry editor and delete a specific file under the Windows\runsystem, but I couldn't access runsystem. Another said to delete all restoration points by turning restoration pts off, but there are some things I don't want to lose.

I've been working with it for a while with my minor experience, and all the virus is doing is adding temporary fills like there's no tomorrow. It's slowing my good computer down. Trend Micro PCcillin has found the source, but can't quarentine it.

So:
1.) What am I dealing with? Is it dangerous?

2.)
Please help me through the process to get rid of BKDR_SDBOT.DAB.
(Laptop. Windows XP)

3.)
If I turn off restoration pts, and by doing so delete all former points, how does that help me get rid of the virus? And how would I get to continue running my computer normally?

3b.) If I do restore to a point at a date I'm positive the virus had not been attained yet, what would happen to all stored points after that date, and subsequently, the files the virus is in?

3c.) What all will I lose if I set a restore point back. Word files? Game saves?

Thank you very much for any help.

You sound a little panicky...take a deep breath and calm down ;)

1. SDBot is often referenced as the Spybot worm (not to be confused with Spybot S+D). It's curable, depending on how far it has progressed.

2. ;)

3./3b. You already know that a restore point is a rollback option. When a restore point is set it's basically a snapshot of the entire system including malware taken at the time the point was set. You can't really be sure which points are infected until you roll back to them so it's best to play it safe and lose all of them. It won't delete the bug but it will prevent you from using an infected restore to re-sick your system. Dumping restore points is like deleting an old email -it doesn't hurt operation one whit. Using an older point doesn't alter the newer ones; they're still in the system and still have the potential to re-infect you.

3c. Potentially a lot could be lost in rollback, including Windows updates since that point...you'll lose a lot more by having to reinstall the OS due to malware corruption.

The quickest and easiest way to kill it is to get Malwarebytes AntiMalware (MBAM). Download, install, update, and scan (Quick scan in normal boot, or Full scan in Safe mode)

To be on the safe side, post the log before you tell it to clean. Cleaning may require a restart. (any of the mods+ are welcome to pick up from here as well)

Hello and welcome.. Thanks for assisting. I would just like to say I prefer we KEEP the the restore points for now . We will clen them later. I'd rather have an infected point than none should something go wrong.

Well in case it helps Here's complete MBAM instructions.
Next run MBAM (MalwareBytes):

NOTE: Before saving MBAM please rename it to zztoy.exe....now save it to your desktop.

Please download Malwarebytes Anti-Malware and save it to your desktop.
alternate download link 1
alternate download link 2

MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Thanks so much for the help and getting back to me so quickly.

I just got the free download for MBAM thinking a demo subscription should be enough. Let me know if I should have bought the full program. Anyway, the quick scan keeps freezing the program. MBAM scan will get all the way to "final scanning" under the scanning process, and then it will no longer respond. This has happened at least three times. I've turned off Trend Micro PC-cillin in hopes that that will help, but if it doesn't... what should I do?

Another option is MBAM Full Scan in Safe mode.....just don't wanna see it forgotten in the shuffle ;) Boop, it's all yours :D

And Demo MBAM is perfectly effective for on demand scanning, full mode gets you real time protection.
