    Your advice helped me to remove disk antivirus professional from my PC.

    Thank you very much for saving my data and me.

    I need one more help. I’m based in Mumbai, India. I don’t have licensed anti virus software in my computer. I’m using windows 7 ultimate 64 bit. We do browse internet, down songs & email. Please advise me which an anti virus software which is easy to remove after a month / expiry and again re-install. As per my exprience, it is easy to install first time such free antivirus sofrware but unable to remove completely and re-install again and even some times doesn’t allow other antivirus software to load in PC. Such free anti virus software do create problems to operating system and make PC slow and ultimately one has to re-install an opearting system. Please advise me. Regards, -Bhavin

  • Steve no longer grim.

    Really just repeat what has been said above many thanks for your advice, I’ve had a similar bug to this one before and before I could fix it the hard drive stopped working so when it happened again I was just totally freaking out. It’s running the malware bytes scan at the mo and I can see its already found some of the little blighters which are causing the problems so thank you so so much. I did the full scan, I seem to think the quick scan option is sufficient so maybe consider adding that to your advice above. Cheers. Steve.

  • Laura

    What do I do if the disc antivirus thing won’t allow me to download the malware bytes software??

    • Stelian Pilici

      Hello Laura,
      Please start your computer in Safe Mode with Networking, and then download this tool:

      1. Remove all floppy disks, CDs, and DVDs from your computer, and then restart your computer.
      2. Do one of the following:
        • If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you will need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.
        • If your computer has more than one operating system, use the arrow keys to highlight the operating system you want to start in safe mode, and then press F8.
      3. On the Advanced Boot Options screen, use the arrow keys to highlight Safe Mode with Command Prompt, and then press ENTER. For more information about options, see Advanced startup options (including safe mode).

    We use Windows XP. I was suspicious of this [app] when it wanted money to run; then I found your article. The bugger actually blocked Malwarebytes when I tried to download it. But my wife and I have separate user logins, and it had only infected mine. I was able to use hers to clean everything out.
    Thank you.

  • Gene

    Worked great—-many many thanks for the help
