I turn on the computer today and see that the BIOS says "Loading Default BIOS Settings due to checksum issue" or something similar to that. I thought nothing of that so when I login the Action Center and the internet icons are missing (showing up as blank) on my taskbar. Microsoft Security Essentials also has been reset saying I have to re download spyware definitions. The computers time has been reset as well to 11:00PM 12/31/2007. I think i'm infected :(

EDIT: I am so sorry for posting this in the Windows 7 I meant to post it in the Am I infected. Can a mod please move this topic?

Welcome, can you do these??

Please download MiniToolBox, save it to your desktop and run it.

Checkmark the following checkboxes:

Click Go and post the result (Result.txt). A copy of Result.txt will be saved in the same directory the tool is run.

Note: When using "Reset FF Proxy Settings" option Firefox should be closed.



Next run Superantisypware (SAS):

Please download and scan with SUPERAntiSpyware Free
  • Double-click SUPERAntiSypware.exe and use the default settings for installation.
    For instructions with screenshots, please refer to the How to use SUPERAntiSpyware to scan and remove malware from your computer Guide.
  • An icon will be created on your desktop. Double-click that icon to launch the program.
  • If it will not start, go to Start > All Prgrams > SUPERAntiSpyware and click on Alternate Start.
  • 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 other options as they are set):
    • 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 "Select Scan Type" check the box for Complete Scan.
  • If your computer is badly infected, be sure to check the box next to Enable Rescue Scan (Highly Infected Systems ONLY).
  • Click the Scan your computer... button.
  • 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 scan log after reboot, launch SUPERAntiSpyware again.
  • Click the View Scan Logs button at the bottom.
  • This will open the Scanner Logs Window.
  • Click on the log to highlight it and then click on View Selected Log to open it.
  • Copy and paste the scan log results in your next reply.
-- Some types of malware will disable security tools. If SUPERAntiSpyware will not install, please refer to these instructions for using the SUPERAntiSpyware Installer. If SUPERAntiSpyware is already installed but will not run, then follow the instructions for using RUNSAS.EXE to launch the program.



Please download TDSSKiller.zip and and extract it.
  • Run TDSSKiller.exe.
  • Click on Change Parameters
  • Put a check in the box of Detect TDLFS file system
  • Click Start scan.
  • When it is finished the utility outputs a list of detected objects with description.
    The utility automatically selects an action (Cure or Delete) for malicious objects.
    The utility prompts the user to select an action to apply to suspicious objects (Skip, by default). Let the options as it is and click Continue
  • Let reboot if needed and tell me if the tool needed a reboot.
  • Click on Report and post the contents of the text file that will open.

    Note: By default, the utility outputs the log into system disk (it is usually the disk with installed operating system, C:\) root folder. The Log has a name like: TDSSKiller.Version_Date_Time_log.txt.




Please download aswMBR ( 511KB ) to your desktop.
  • Double click the aswMBR.exe icon to run it
  • Click the Scan button to start the scan
  • On completion of the scan, click the save log button, save it to your desktop and post it in your next reply.

OK,it looks clean any issues left?
I would say most likely your infections came via a torrent download. They are amzingly popular around here.

Make sure all your Adobe stuff is fully updated.

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 Posted Image > 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.

Ok I created the restore points and removed the old ones.
I have been downloading from torrents only because downloading directly is slow for me.
Overall everything seems alright.
Thank you :lol:
