I've been hit with System Check and the associated google redirects virus. I tried following the instructions in the Remove System Check post, but RKill doesn't find anything to terminate in safe mode, and I cannot get TDSSKiller to run (the Run box comes up, I click yes, and nothing happens). I ran MBAM but it didn't find anything (probably because the previous two programs were outsmarted, right?). What do I do now? (I'm currently working through the steps to prepare for the Malware Removal forum, though I'm not actually sure whether I have the 32 or 64 bit Windows 7 - how do I find that out?)

Thanks!

Thanks! 64-bit, which means I can't run Gmer.

All I can say right now is thank goodness for safe mode... I'll patiently await help. :)

Download the FixTDSS.exe

Save the file to your Windows desktop.
Close all running programs.
If you are running Windows XP, turn off System Restore. How to turn off or turn on Windows XP System Restore
Double-click the FixTDSS.exe file to start the removal tool.
Click Start to begin the process, and then allow the tool to run.
Restart the computer when prompted by the tool.
After the computer has started, the tool will inform you of the state of infection (make sure to let me know what it said)
If you are running Windows XP, re-enable System Restore.

Ok, I ran it and when the computer restarted the message was:
Suspicious use of kernel callback but MBR appears intact. Repair not done.
No infections were found

Also, the google redirect issue appears to have gone away. So apparently something did work on that...

However, System Check did pop up as soon as my computer rebooted. Should I try running MalwareBytes again now?

Thanks!

While my computer was just running, Avira popped up and said it found two active malwares running on my computer and moved them to quarantine. Right before that system check had popped up those annoying 24 windows, and when Avira moved the malware, the remaining three (i was in the process of closing them all) disappeared. Then a blue screen about a data crash dump or something (I had never seen it before) showed up and my computer shut down and restarted. On restart, all my files were back to being hidden (I had unhidden them before, and they had stayed unhidden on the previous couple reboots), but System Check did not pop up for the first time in 3 days.

What should I do now? Maybe we're almost there? Thanks so much.

It is sometimes tough to get it out of the registry. Rebooting after removal is always good.

Sometimes you need to run multiple tools or rescans.

Try running a fresh copy aof RKILL and an updated MBAM scan again. Do NOT reboot between RkILL and MBAM,wait till after.

May as well run SAS too. I need to rewrite this tute as they updated,but it's close enough for now.


Next run Superantisypware (SAS):

Download and scan with SUPERAntiSpyware Free for Home Users
  • Double-click SUPERAntiSpyware.exe and use the default settings for installation.
  • 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 Scanning Control tab.
  • 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.
  • 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.
  • Click "Next" to start the scan. Please be patient while it scans your computer.
  • 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".
  • 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.
If you have a problem downloading, installing or getting SAS to run, try downloading and using the SUPERAntiSpyware Portable Scanner instead. Save the randomly named file (i.e. SAS_1710895.COM) to a usb drive or CD and transfer to the infected computer. Then double-click on it to launch and scan. The file is randomly named to help keep malware from blocking the scanner.

Ok, RKill didn't find anything, and MBAM found 2 things (let me know if you want the full log):
Registry Data Items Detected: 2
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced|Start_ShowMyComputer (PUM.Hijack.StartMenu) -> Bad: (0) Good: (1) -> Quarantined and repaired successfully.
HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced|Start_ShowSearch (PUM.Hijack.StartMenu) -> Bad: (0) Good: (1) -> Quarantined and repaired successfully.

I also ran Avira, and it found and quarantined three items (again, let me know if you want the full log):
Starting the file scan:

Begin scan in 'C:\' <Gateway>
C:\Users\Katie\AppData\LocalLow\Sun\Java\Deployment\cache\6.0\10\78f4a48a-3956060f
[0] Archive type: ZIP

Beginning disinfection:

[DETECTION] Contains recognition pattern of the EXP/2011-3544.F exploit
[NOTE] The file was moved to the quarantine directory under the name '0391a407.qua'.


Also, I just noticed that there's actually a shortcut (hidden) on my desktop to System Check, and the properties say, under Target: C:\ProgramData\5Phf240m5UZGBh.exe

I looked under Program Data and it looks like there are 3 related files there. I didn't want to just delete them in case they might screw up other things.

I tried checking google again, and the redirects were back, so I re-ran FixTDSS and that was gone again when the computer rebooted. I'll try running SAS with your directions now.

Thanks for the help.

SAS only found adware tracking cookies - nothing to quarantine or delete. What's next?

I re-ran FixTDSS and that was gone again ..what was gone again?

Are you on a router? Are other machines on it,if so are they redirecting?

Do you use Firefox?

When a browser runs an applet, the Java Runtime Environment (JRE) stores the downloaded files into its cache folder (C:\Documents and Settings\username\Application Data\Sun\Java\Deployment\cache) for quick execution later and better performance. Malicious applets are also stored in the Java cache directory and your anti-virus may detect them and provide alerts. For more specific information about Java exploits, please refer to Virus found in the Java cache directory.

Notification of these files as a threat does not always mean that a machine has been infected; it indicates that a program included the viral class file but this does not mean that it used the malicious functionality. As a precaution, I recommend clearing the entire cache to ensure everything is cleaned out:[list=1][*]Clear the Java cache
[*]Clear the browser cache in Internet Explorer

Sorry for the ambiguity! The google search redirects were gone again after re-running FixTDSS.

I do run Firefox, and I am on a wireless router (and the other computers are not having the same problems). I'll try clearing the java cache. Thanks!

Should I be concerned/do anything about the System Check shortcut sitting on my desktop, taunting me?

Clearing the java cache didn't seem to do anything (upon restarting my computer this morning, the google redirects were back again - running FixTDSS gets rid of the redirects, but only until I shut down and restart my computer - then they return).

Also, I'm probably getting ahead of myself, but is there a way to get all my programs to show up on my desktop and start menu again? Right now files and folders that were on my desktop are showing up (though shaded, because they are still hidden, I guess), but programs I have to search for.

Anyway, thanks again for your help!

OK ,if this doesn't help..... In FireFox it may be the Add ons/Plugins. try disabling them one at a time and see which one was at fault.

How to disable extensions and plugins

Keeping your third-party plugins up to date


Then .... We need a deeper look. Please go here....
Preparation Guide ,do steps 6 - 9.

Create a DDS log and post it in the new topic explained in step 9,which is here Virus, Trojan, Spyware, and Malware Removal Logs and not in this topic,thanks.
If Gmer won't run,skip it and move on.
Include a link back to this topic.

Let me know if that went well.

Thank you!
Now that your log is properly posted, you should NOT make further changes to your computer (install/uninstall programs, use special fix tools, delete files, edit the registry, etc) unless advised by a Malware Removal Team member, nor should you continue to ask for help elsewhere. Doing so can result in system changes which may not show it the log you already posted. Further, any modifications you make on your own may cause confusion for the helper assisting you and could complicate the malware removal process which would extend the time it takes to clean your computer.

From this point on the Malware Removal Team should be the only members that you take advice from, until they have verified your log as clean.

Please be patient. It may take a while to get a response because the Malware Removal Team members are very busy working logs posted before yours. They are volunteers who will help you out as soon as possible. Once you have made your post and are waiting, please DO NOT make another reply until it has been responded to by a member of the Malware Removal Team. Generally the staff checks the forum for postings that have 0 replies as this makes it easier for them to identify those who have not been helped. If you post another response there will be 1 reply. A team member, looking for a new log to work may assume another MRL Team member is already assisting you and not open the thread to respond.

The current wait time is 1 - 5 days and ALL logs are amswered.

To avoid confusion, I am closing this topic.
