    "Windows Warning"

    Recently took advantage of free upgrade from OS 8-1.

    Am writing this from desktop (win7-64).

    My Acer laptop has been functioning alright with OS10 until today. Upon opening I get following screen:

    Large but faint background with WARNING and message to effect computer has security error. A small clearer box has:

    "Windows Warning

    Security error detected, due to suspicious activity found on your computer.
    Please contact Microsoft Certified Technician for help.
    (020) 3805 0589 (toll free)

    Tried cold booting without success in removing this message. Ran KIS full scan - no problem ! Ran Malwarebytes and removed some 207 POBs (or what they are entitled)

    This screen is still appearing.

    Urgent advice appreciated please.

    Google that phone number and you'll see why you should not react to it !
    Also run your normal AV program (other than MalwareBytes) to hopefully remove the warning source.

    Many thanks for you prompt and helpful reply.

    Strange that Kaspersky Internet Security - which is up to date - nor Task Manager showed up the problem.

    Try these stand alone malware utilities.

    Restart your machine in case there are any system operations pending

    Click here to download Old Timer-TFC.
    >> save the application to your Desktop.
    :info: Old Timer-TFC is a standalone application, there is no install.

    :warn:Save your work and close all open windows.
    TFC will close ALL open programs including your browser!

    Right click, run as administrator TFC

    Click the Start button to begin the cleaning up temporary files and folders.
    :warn: Do not work on other things while TFC is running - most applications use some sort of temporary files. Just let TFC run by itself on the machine until it completes.

    Restart your machine immediately after TFC completes.

    AdwCleaner is a two step process. Scan then Clean

    Click here to download AdwCleaner (author: Xplode)
    --> save the application to your Desktop.

    • Right-click AdwCleaner.exe on your Desktop and select Run As Administrator to run the scanner with full privilege rights.
      AdwCleaner is a standalone executable, there is no install.

    • Click on the Scan button.
      • AdwCleaner begins scanning your system. It might take some time to complete.

      • Review the detected objects grouped under each of the tabs.
        --> If there is something you KNOW should NOT be cleaned, clear the checkbox next to the object. If you're not sure about an object, paste the scan logfile (AdwCleaner[R#].txt) in a new post for a member to review and advise you.
        Otherwise, go to the next step.

    • After the scan has finished and you have reviewed the objects to be cleaned, click on the Clean button.
      • Answer OK to the close all programs prompt, then follow the onscreen prompts.
      • Answer OK to the restart the computer prompt to complete the removal process.
        The AdwCleaner log file is opened in your default Text editor when the machine has restarted.
        Each time AdwCleaner runs, the log file number [#] is incremented, the highest number is the most recent. There are two log files, one for the scan (AdwCleaner[R#].txt) and one for the clean (AdwCleaner[S#].txt).

    Paste the entire clean logfile (AdwCleaner[S#].txt) in your next post.
    --> AdwCleaner logs are located in the C:\AdwCleaner folder if you need to reference them again

    You can also run ZHPCleaner by Nicolas Coolman and RogueKiller.

    Be advised that ZHPCleaner sometimes shows false positives. Check the logs before cleaning. You can untick whatever you do not want to remove first.

    Thank you all very much for your time and most helpful advice.

    As I am using my desktop (Win7-64) will take some time to get my head around the Win 10 laptop. Not sure if I can send mail yet. Oh to be young and computer literate. Now if I was a teenager...
