    my mate gave me his laptop and ask me to have a look at it because he keeped getting pop ups and virus alarts so i had a look and i installed zonealarm Security suite on it and ran a virus scan and spyware scan i found 2 infected files and deleted it but he still keeps getting pop ups so i googled it and found this website and i was suprised what i was reading. my friend uses limewire pro alot and he might have got it from there. i told him if he had any recovery CDs he said no he said he only had a restore save point and if i restore it back would the worm follow does anyone know ????

  • 26 }
    webmaster (author) said:

    It depends on the restore points, if he was alredy infected when the restore point was created, the problem remains.

    Best thing to do is run HiJackThis and post the result on Bleepingcomputer or your laptop manufacturer’s own Forum. They can analyze and give you a view of what are the threats on your computer.

    I have virus. Please let me know how this can be removed, before the damage is done. I tried smitfraudfix but it does not work. Is there any free removal tool you suggest?

  • 44 }
    webmaster (author) said:

    Mr. Divakar,

    If you have followed the removal procedure carefully you should have fixed it. If not, you may go to sites that can analyze HJT files such as and Go and post your HJT logs there so that they can analyze it.

    nathan said:

    These all seem like very complex routes to try and get rid of this myzor malware. I simply logged onto my computer in safe mode (F8 when you boot it up. I selected the applications mode so i could access the internet. Then I downloaded Windows DEFENDER free from the microsoft website and ran it, and then downloaded spybot search and destroy free (do a google search), and ran that also. You get prompted to re boot your computer and then all worked just fine, and for free too. BONUS. Hope it works for you too

    got infected by this worm
    help plz……
    how to download the free software?

  • 56 }
    Bizzle said:

    This software is more annoying than a virus itself. The bubbles pop up literally every five seconds telling you that your computer is infected. If you get a virus, just do a system restore back to the last update before the virus got on your computer. It will restore your computer to the way it was before the virus hit. Just go to start, help and support center. When the window opens, click on system restore. Click the option to restore my computer to an earlier time. Choose a date before you got the virus. It may be a good idea to back up important documents and music. That is a good thing to do regardless. Good luck!
