Posted 21 March 2010 - 10:47 AM

I have been battle-ing this computer since mid-october. Most often the only time I can connect to the internet is while in safe mode. But now when I attempt to boot in safe mode I just get a black screen that says safe mode in each corner and Micrsoft Windows XP (Build 2600.xpsp_sp2.gdr.070221-2254: Service Pack 2) at the top.

All of my virus scanners are out dated since I cannot connect to the internet on that computer. I did get Kaspersky to run last night and it kept finding backdoor.win32.sinowal.c in the System folder. It stated that it was disinfected but each reboot and new scan would find it again.

Issues that the computer is presenting: will not detect cd's, or flash drives, will not connect to the internet unless it's in safe mode, safe mode will no longer finish starting up (as of this morning), When I attempt to run virus/malware/etc scanners the computer freezes up, wont shut down unless it's a hard shut down.

Things I have tried: rkill, kaspersky 2010, KK (from Kaspersky.com), which ran successfully but didn't solve any issues. SuperAnti Spyware, Malware Bytes, AVG, Ad-ware, Spybot S&D (which all frozen upon opening) I've also tried to look through my task manager and check to see in anything I didn't recognize was on the bad list on bleeping computer.

I'm currently using a different computer (obviously). Any help with my infected computer would be greatly appreciated.

Thanks, LB

lb83,

Please try re-running Malwarebytes after following these instructions.

Click on Start, then Run. Type "C:\Program Files\Malwarebytes' Anti-Malware" ( with the quotes ) and press Enter.

Once in that folder, find MBAM.EXE. Right Click on MBAM.EXE and rename it to zztoy.exe and press enter.

Now, double click on zztoy.exe and see if Malwarebytes will open. If it will, please run a scan and post the results in you reply.

Thank you for helping me out!

I renamed the file.
It opens just fine but freezes up every time at 5 seconds unless I'm in safe mode. Then it runs fine, which I'm guessing will do no good.
Here is the log from the safe mode scan anyways.

If you are able to run SuperAntispyware in Safe Mode with Networking, please do so.

Please be sure you update SAS before scanning and post the log from the scan.

Kaspersky removed Super Anti Spyware.
When I attempted to reinstall it I received the message " The system administrator has set policies to prevent this installation." Even while logged in under the admin.

Ok. let's try these instructions for SAS.

SAS, may take a long time to scan
Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.If you are using Vista, right-click on the file and choose Run As Administrator.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If asked to update the program definitions, click "Yes". If not, update the definitions before scanning by selecting "Check for Updates". (If you encounter any problems while downloading the updates, manually download them from here. Double-click on the hyperlink for Download Installer and save SASDEFINITIONS.EXE to your desktop. Then double-click on SASDEFINITIONS.EXE to install the definitions.)
  • In the Main Menu, click the Preferences... button.
  • Click the "General and Startup" tab, and under Start-up Options, make sure "Start SUPERAntiSpyware when Windows starts" box is unchecked.
  • Click the "Scanning Control" tab, and under Scanner Options, make sure the following are checked (leave all others unchecked):
    • Close browsers before scanning.
    • Scan for tracking cookies.
    • Terminate memory threats before quarantining.
  • Click the "Close" button to leave the control center screen and exit the program.
  • Do not run a scan just yet.
  • First
Reboot your computer in "Safe Mode" using the F8 method. To do this, restart your computer and after hearing your computer beep once during startup (but before the Windows icon appears) press the F8 key repeatedly. A menu will appear with several options. Use the arrow keys to navigate and select the option to run Windows in "Safe Mode".

Scan with SUPERAntiSpyware as follows:
  • Launch the program and back on the main screen, under "Scan for Harmful Software" click Scan your computer.
  • On the left, make sure you check C:\Fixed Drive.
  • On the right, under "Complete Scan", choose Perform Complete Scan and click "Next".
  • After the scan is complete, a Scan Summary box will appear with potentially harmful items that were detected. Click "OK".
  • Make sure everything has a checkmark next to it and click "Next".
  • A notification will appear that "Quarantine and Removal is Complete". Click "OK" and then click the "Finish" button to return to the main menu.
  • If asked if you want to reboot, click "Yes" and reboot normally.
  • To retrieve the removal information after reboot, launch SUPERAntispyware again.
    • Click Preferences, then click the Statistics/Logs tab.
    • Under Scanner Logs, double-click SUPERAntiSpyware Scan Log.
    • If there are several logs, click the current dated log and press View log. A text file will open in your default text editor.
    • Please copy and paste the Scan Log results in your next reply.
  • Click Close to exit the program.
Note.. SAS doesn't open the registry hives for other user accounts on the system, so scans should be done from each user account.

I tried one more time to install SAS. I turned it on and when I came back from lunch an hour later it had finally finished preparing to install!
I ran the program as suggested and here is my log:

Please download mbr.exe and save it to your desktop.
Doubleclick on mbr.exe to run it (if you use Windows Vista or 7, right click on the file and select "run as administrator).
You will see a command window flashing and afterwards you can find the log on the desktop (mbr.log).
Please post its contents in your next reply.

Hello there,

You have a serious rootkit there. Since the tools we need to fix this are not allowed in this forum, I am moving this topic to the Malware Removal forum.

Please download HelpAsst_mebroot_fix.exe and save it to your desktop.
Close out all other open programs and windows.
Double click the file to run it and follow any prompts.
If the tool detects an mbr infection, please allow it to run mbr -f and shutdown your computer.
Upon restarting, please wait about 5 minutes, click Start>Run and type the following bolded command, then hit Enter.

helpasst -mbrt

Make sure you leave a space between helpasst and -mbrt !
When it completes, a log will open.
Please post the contents of that log.


*In the event the tool does not detect an mbr infection and completes, click Start>Run and type the following bolded command, then hit Enter.

mbr -f

Now, please do the Start>Run>mbr -f command a second time.
Now shut down the computer (do not restart, but shut it down), wait a few minutes then start it back up.
Give it about 5 minutes, then click Start>Run and type the following bolded command, then hit Enter.

helpasst -mbrt

Make sure you leave a space between helpasst and -mbrt !
When it completes, a log will open.
Please post the contents of that log.

**Important note to Dell users - fixing the mbr may prevent access the the Dell Restore Utility, which allows you to press a key on startup and revert your computer to a factory delivered state. There are a couple of known fixes for said condition, though the methods are somewhat advanced. If you are unwilling to take such a risk, you should not allow the tool to execute mbr -f nor execute the command manually, and you will either need to restore your computer to a factory state or allow your computer to remain having an infected mbr (the latter not recommended).

regards, Elise

HelpAsst has been open for about three hours now and doesn't appear to be doing anything. It still says checking mbr with a flashing cursor
Is this typical or should I try a different route? I opened it by double clicking the icon on the desktop.
