    Trying to reinstall MSE- error code 0x80070643


    Hello,

    I had MSE installed and removed it because I kept getting error 0x800106ba when trying to run a full scan on my computer. I've been trying to reinstall MSE but keep getting error 0x80070643. My Windows firewall is on. I have no other anti-virus program installed. I've restarted my computer and tried reinstalling MSE and still get this error code 0x80070643. I tried repairing Microsoft .Net Framework 4.5.2.

    I would really like to have MSE installed so your assistance in resolving this issue would be greatly appreciated.

    Thank you.

    The error message in this thread/post...

    ...is different - but maybe the info will help you.

    Hello,

    Thank you for the suggestion but I'm not a tech person but it appears this thread is about uninstalling MSE and cleaning the registry- a lot of information which I don't understand!

    To see if a virus may have caused the conflict .... I'd like you to scan your machine with ESET OnlineScan
    1. Hold down Control and click on the following link to open ESET OnlineScan in a new window.
      ESET OnlineScan
    2. Click the button.
    3. For alternate browsers only: (Microsoft Internet Explorer users can skip these steps)
      1. Click on to download the ESET Smart Installer. Save it to your desktop.
      2. Double click on the icon on your desktop.
    4. Check
    5. Click the button.
    6. Accept any security warnings from your browser.
    7. Check
    8. Push the Start button.
    9. ESET will then download updates for itself, install itself, and begin scanning your computer. Please be patient as this can take some time.
    10. When the scan completes, push
    11. Push , and save the file to your desktop using a unique name, such as ESETScan. Include the contents of this report in your next reply.
    12. Push the button.
    13. Push

    Hello,

    I've completed the scan. There wasn't a "list of found threats" option since the scan came back with no threats found. What should my next step(s) be?

    Thank you.

    So was it working before the last update was issued?

    The last MSE definition update was done on 9/13/15 definition 1.205.2377.0). Is this the update you're referring to? I was able to run a quick scan but when I tried the full scan, the scan would get about 3/4 done and then I got a message "your PC couldn't be scanned " and the error code 0x800106ba. I decided to do a full scan because I received an email from my internet provider (Cox) on 9/13/15 stating "Cox has identified that one or more computers/ devices behind your cable modem maybe infected with the FakeSecSen or "Spy Sheriff" Virus. A device behind your cable modem appears to have connected to a command and control server affiliated with this malware."

    Thank you for your continued assistance in helping me try to resolve this issue.

    Please download Junkware Removal Tool to your desktop.
    • Disconnect from the Internet, shut down your protection software now to avoid potential conflicts.
    • Run the tool by double-clicking it. If you are using Windows Vista, 7, or 8; instead of double-clicking, right-mouse click JRT.exe and select "Run as Administrator".
    • The tool will open and start scanning your system.
    • Please be patient as this can take a while to complete depending on your system's specifications.
    • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
    • Post the contents of JRT.txt into your next message.
