  2. hey it is me again forgot to tell you but I have something called Security Central I think that has something to do with the Blaster Worm the only way I can delete Security Central is activate it but I do not want to do that cause I have to buy something that is unknown to me just need help removing the blaster worm and the security central thank you again

    • In your case W32 Blaster.Worm is fake infection probably. Get a good antivirus/antispyware, and not a “virus protector” or security central/ which is scam. I would recommend scanning with Spyware Doctor.

  3. Hi, my personal computer has been infected with the W32/Blaster.worm and I have no way of accessing the internet because of it so I can’t download any removal software. Is there a way to remove it without the access or do I need to take it to a professional to remove? Thank you.

  4. @Sherilyn Froehlich
    I have the same problem. I can’t access any applications, I get a message everything is infected. How can I kill this process manually? What happens if I shut down my PC – will I be able to start it again?

    • Shir: Look up more info by the name of antivirus it advertises. W32.Blaster is used by quite a lot of fake antiviruses and removal instructions might differ

    • Ted: download process explorer or another PC, and move it to infected PC through USB. Launch it and see what processes are running from %TEMP or %Application Data. Stop them.
