My cpu has been working slow of late. Normally this is not such a concern. My majic jack has been randomly rebooting every two minutes or so. Additionally, I have noticed a few small administrative changes on my system. Spybot scans are coming up empty. After downloading an update to Spybot, i have noticed that it's name on my desktop has been changed. This leads me to believe that Spybot has been compromised. Please tell me how to proceed. Thank you in advance.

Please download Malwarebytes Anti-Malware (v1.44) and save it to your desktop.Download Link 1
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.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • 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.FYI: mvps.org is no longer recommending Spybot S&D or Ad-Aware due to poor testing results. See here - (scroll down and read under Freeware Antispyware Products)

Further, most people don't understand Spybot's TeaTimer or how to use it and that feature can cause more problems than it's worth. TeaTimer monitors changes to certain critical keys in Windows registry but does not indicate if the change is normal or a modification made by a malware infection. The user must have an understanding of the registry and how TeaTimer works in order to make informed decisions to allow or deny the detected changes. Additionally, TeaTimer may conflict with other security tools which do a much better job of protecting your computer and even prevent disinfection of malware by those tools.

More effective alternatives are Malwarebytes Anti-Malware and SUPERAntiSpyware Free.

Please perform a scan with Kaspersky Online Virus Scanner.
-- Requires free Java Runtime Environment (JRE) to be installed before scanning for malware as ActiveX is no longer being used.
-- This scan will not remove any detected file threats but it will show where they are located so they can be cleaned with other tools.
  • Vista users: need to right-click either the IE or FF Start Menu or Quick Launch Bar icons and select Run As Administrator) from the context menu.
  • Read the "Advantages - Requirements and Limitations" then press the Posted Image... button.
  • You will be prompted to install an application from Kaspersky. Click the Run button. It will start downloading and installing the scanner and virus definitions.
  • When the downloads have finished, you should see 'Database is updated. Ready to scan'. Click on the Posted Image... button.
  • Make sure these boxes are checked. By default, they should be. If not, please check them and click on the Posted Image... button afterwards:
    • Detect malicious programs of the following categories:
      Viruses, Worms, Trojan Horses, Rootkits
      Spyware, Adware, Dialers and other potentially dangerous programs
    • Scan compound files (doesn't apply to the File scan area):
      Archives
      Mail databases
  • Click on My Computer under the Scan section. OK any warnings from your protection programs.
  • The scan will take a while so be patient and do NOT use the computer while the scan is running. Keep all other programs and windows closed.
  • Once the scan is complete (the 'status' will show complete), click on View Scan Report and any infected objects will be shown.
  • Click on Save Report As... and change the Files of type to Text file (.txt)
  • Name the file KAVScan_ddmmyy (day, month, year) before clicking on the Save button and save it to your Desktop.
  • Copy and paste (Ctrl+C) the saved scan results from that file in your next reply.
-- Note: Some online scanners will detect existing anti-virus software and refuse to cooperate. You may have to disable the real-time protection components of your existing anti-virus and try running the scan again. If you do this, remember to turn them back on after you are finished.

Remove the infected file(s) found by Kaspersky in the following location:
C:\Documents and Settings\Default User\Local Settings\History\svchost.exe

Malwarebytes Anti-Malware has a built-in FileAssassin feature for removing stubborn malware or other malicious files that it did not detect.
  • Go to the "More Tools" tab and click on the "Run Tool" button
  • Browse to the location of the file(s) to remove using the drop down box next to "Look in:" at the top.
  • When you find the file, click on it to highlight, then select Open.
  • You will be prompted with a message warning: This file will be permanently deleted. Are you sure you want to continue?. Click Yes.
  • If removal did not require a reboot, you will receive a message indicating the file was deleted successfully.
  • Click Ok and exit MBAM.
  • If prompted to reboot, then do so immediately.
-- If the file returns, then you probably have other malware on your system which is protecting or regenerating it.

Caution: Be careful what you delete. FileAssassin is a powerful program, designed to move highly persistent files. Using it incorrectly could lead to serious problems with your operating system.


The other detections are in Housecalls Quaratine folder. When an anti-virus or security program quarantines a file by renaming and moving it into a virus vault (chest) or a dedicated quarantine folder, that file is essentially disabled and prevented from causing any harm to your system. The quarantined file is safely held there and no longer a threat until you take action to delete it. One reason for doing this is to prevent deletion of a crucial file that may have been flagged as a "false positive" especially if the scanner uses heuristic analysis technology. Heuristics is the ability of a scanning program to detect possible new variants of malware before the vendor can get samples and update the program's definitions for detection. Heuristics uses non-specific detection methods to find new or unknown malware which allows the anti-virus to detect and stop if before doing any harm to your system. The disadvantage to using heuristics is that it is not as reliable as signature-based detection (blacklisting) and can potentially increase the chances that a non-malicious program is flagged as suspicious or infected. If that is the case, then you can restore the file and add it to the exclusion or ignore list. Doing this also allows you to view and investigate the files while keeping them from harming your computer. Quarantine is just an added safety measure. When the quarantined file is known to be malicious, you can delete it at any time. Keep in mind, however, that if these files are left in quarantine, other scanning programs and security tools may flag them as a threat while in the quarantined area so don't be alarmed if you see such an alert. Just delete the quarantined items and subsequent scans should no longer detect them.

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 perform a scan with SUPERAntiSpyware Online Safe Scan.
  • Be sure to follow the instructions provided on that same page.
  • When the scan is complete, please post the results in your next reply.

You're welcome.

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.
