Hey guys... I have a start up error that has been going on for the past couple of days. Everytime the computer boots up it starts up and brings up this Windows explorer has encountered a problem and needs to close. We are sorry for the inconvenience. All I have to do is start tsk manager and start explorer.exe once it crashes. then I am fine. It is very annoying though so it would be nice to fix it.

The data report says.

AppName: explorer.exe AppVer: 6.0.2900.5512 ModName: ws2_32.dll
ModVer: 5.1.2600.5512 Offset: 00006a55


One more thing...

Once I click don't send on the report the screen goes away and in the upper left hand corner this little box comes up and says " Setting up personal settings for C:\Sud\SSOW\sep.exe" Then explorer will reappear and everything will be back to normal. I don't know if that has any significance.

Thanks

I have also been getting this error..
AppName: explorer.exe AppVer: 6.0.2900.5512 ModName: unknown
ModVer: 0.0.0.0 Offset: 71ab6a55

Please download Malwarebytes Anti-Malware (v1.42) 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.

-- If Malwarebytes Anti-Malware results in any error messages, check the Help file's list of error codes within its program folder first. If you do not find any information, please refer to Common Issues, Questions, and their Solutions, Frequently Asked Questions. If the error you are receiving is not in the list, please report it here so the research team can investigate.

Please download TFC (Temp File Cleaner) by Old Timer and save it to your desktop.
alternate download link
  • Save any unsaved work. TFC will close ALL open programs including your browser!
  • Double-click on TFC.exe to run it. If you are using Vista, right-click on the file and choose Run As Administrator.
  • Click the Start button to begin the cleaning process and let it run uninterrupted to completion.
  • TFC will clear out all temp folders for all user accounts (temp, IE temp, Java, FF, Opera, Chrome, Safari), including Administrator, All Users, LocalService, NetworkService, and any other accounts in the user folder.
  • Important! If TFC prompts you to reboot, please do so immediately. If not prompted, manually reboot the machine anyway to ensure a complete clean.
Note: It is normal for the computer to be slow to boot after running TFC cleaner the first time.

Please download Norman Malware Cleaner and save to your desktop.
alternate download link
  • Be sure to print out the instructions provided on the same page.
  • Restart your computer in "Safe Mode".
  • Double-click on Norman_Malware_Cleaner.exe to start the program.
  • Read the End User License Agreement and click the Accept button to open the scanning window.
  • Click Start Scan to begin.
  • In some cases Norman Malware Cleaner may require that you restart the computer to completely remove an infection. If prompted, reboot and run the tool again to ensure that all infections are removed.
  • After the scan has finished, a log file with the date (i.e. NFix_2009-06-22_07-08-56.log) will be created on your desktop with the results.
Note: For usb flash drives and/or other removable drives to scan, use the Add button to browse to the drives location, click on the drive to highlight and choose Ok.

Now rescan again with Malwarebytes Anti-Malware, but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

Don't forget to perform the other scan with Norman.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Start > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Posted Image > Run... and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.
Vista and Windows 7 users can refer to these links: Create a New Restore Point in Vista or Windows 7 and Disk Cleanup in Vista.

You're welcome.

Tips to protect yourself against malware and reduce the potential for re-infection:

Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Avoid gaming sites, porn sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs (i.e. Limewire, eMule, uTorrent). They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans, and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. Porn sites can lead to the Trojan.Mebroot MBR rootkit and other dangerous malware. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.Beware of Rogue Security software as they are one of the most common sources of malware infection. They infect machines by using social engineering and scams to trick a user into spending money to buy a an application which claims to remove malware. For more specific information on how these types of rogue programs and infections install themselves, read:Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk as they are one of the most common infection vectors for malware which can transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...

ok... so I came back home for break and plugged my moms usb flash drive in... well now i know where the sed.exe came from. I had zonealarm running when i plugged it in and it instantly flagged that sed.exe was trying to do something. I instantly denied it pulled the drive out and shut the computer down. When i restarted no errors showed up at start, but my time and date settings were messed up... it was put to april 2016. Anyway. I did your exact instructions as posted before, but nothing came up? The only reason I am worried was because of the time and date change that occured... just like last time, but when I go to C:/ the Sud folder is there, but it is empty. All scans came back clean. Any ideas? Thanks. oh and I took the flash drive and just formatted it.

One last thing I forgot to mention. After that first boot I tried to do a system restore, but it failed. I tried twice and it did both times. It was the one I created after the infection was originally cleaned. Was this a cause from the virus is something disabled that is not allowing it to work?

when I go to C:/ the Sud folder is there, but it is empty

Delete the folder and empty your recycle bin.

If System Restore is not working, check to make sure it is started and set to automatic.

Go to Posted Image > Run..., and in the Open box, type: services.msc
  • Locate the System Restore Service and double-click it.
  • Click the "Start" button, then set the startup type in the dropdown box to "Automatic".
  • Press Apply > Ok, then reboot and try using it again.
If its still not working, go to Posted Image > Run..., and in the Open box, type: services.msc
  • Locate the System Restore Service and double-click it.
  • Click the "Stop" button, then set the startup type in the dropdown box to "Disabled".
  • Press Apply > Ok, then reboot.
  • Open My Computer or Windows Explorer, go to Tools > Folder Options > View and check "Show hidden files and Folders", UNcheck "Hide Protected operating system Files (recommended)" and hit Apply > OK.
  • Check the "System Volume Information folder" on each drive and delete its contents (doing this removes all existing restore points).
  • Then reverse the steps where you disabled the service and restart it: Click "Start" and set set the startup type in the dropdown box to "Automatic".
If this still does not help, then follow these steps to "Reinstall System Restore".
