    It works!!! I followed Ryans instructions below (no.3) carefully and I used a Mac to download files and transferred the files to a flash drive and then into the virus affected PC and ran the program including the additional file. I did the longer scan (45mins) to be sure, but the shorter one probably will do as well.
    Saved $80-100 in a repair shop by following these instructions! Thank you, thank you,

    what program should we use?

  • fifty

    fuc..kin virus.pls somebody help me i have to remove it,but thes programs are useles (malwarebytes,super anti spyware,etc)

  • Ryan B

    I too have Windows XP and got the XP Anti Spyware Virus. This is what worked for me:

    I used a free program called Super Anti Spyware. I have used it previously, and it effectively removed the Windows Repair virus when Malwarebytes could not. It’s totally free and it continues to rock my socks off! Go to “” and download the free edition and then transfer it to your infected computer using a cd or usb drive.

    Also, in order to fix the EXE problem where programs won’t load because of a broken file association, I visited “” and followed Venkatesh’s link “”. Inside the zip folder, I found a reg file, which I transferred via usb/ cd, then simply double clicked, and pressed “okay”.

    Abracadabra, my computer was fixed! Hope this works for you too!

    PS. I was able to open Superantispyware and after a couple of scans and quarantines remove the virus completely. Then I used the reg file. If doing them in this order does not work, you might try the reverse (Use reg file first, then wipe out the virus with SuperAntiSpyware).

    PS.S. Make sure to update SuperAntiSpyware, if possible, before scanning. And continue to scan until nothing else needs to be removed.

  • Jonathon

    Malwarebytes did the trick for me

  • marie

    I dont have any of the exe files suggested here. How do I get rid of it?!?!

  • Em

    STOPzilla did not help at all. I downloaded it onto my uninfected computer, then tried transferring it to my infected laptop, and it wouldnt transfer at all! None of this information helped.

  • Jess

    Oh my God, I almost downloaded it.
    I was freaking out because this is my bosses computer and thought I did something, but it kind of seemed weird the internet was informing me of the viral attack instead of the computer so I decided to google it. Wow, jeez, thanks.

    I got a dose of XP AntiSpyware and got rid of it by deleting a bop.exe and a related pf file. It may be a temporary fix but the endlessly annoying popups and fake warnings have disappeared. For some reason McAfee does not even have the bop.exe in its database, which is probably why its AV software doesnt clear it out.
