    Worked a treat – thank you very much! Downloaded the unlocker tool onto a floppy and transferred to infected computer and bingo deleted the file and all works again – Thank you!!

  21. Austin

    I used the unlocker and for some reason my computer completely stopped working. It will turn on but as soon as i log on, all i see is the background picture and thats it. the start menu doesnt come up or anything. is there a way to try and reverse whatever i did?

  22. wamegodreamweaver

    I’ve done all of the above and I’m still getting these messages. I’m unable to open Internet Explorer, Windows Messenger and Yahoo Messenger. The only way I’ve been able to access the internet at all is because I also had Safari on my system. It doesn’t seem to be affected at all. I’ve researched this for 4 days and have tried everything suggested up to and including uninstalling programs, toolbars and utilizing cleaners. Nothing has worked.

    I started getting this message as soon as Internet Explorer did an automatic update. Some of the virus scanners indicate the virus is attached to an Explorer download.

    Help, please.

  23. preciosa1

    I ran into this with IE7 and sure enough, Kiwee Toolbar had been installed on the PC. I uninstalled that (and any other related programs), uninstalled IE7 (bringing it back to IE6), opened IE6, reinstalled IE7 and then everything was fine.

  34. Jess

    I’ve tried uninstalling the kiwee toolbar but it wont let me! I clicked continue then you see a the outline of a box flash up and go away again. Kiwee toolbar just wont uninstall!! I installed Kiwee ages ago…why is it causing a problem for me now? The same message comes up every time……then loads of other writing i dont understand lol. It stops me from going on MSN and internet explorer so im having to use AOL at the moment. Please can someone help!

  35. Mark

    hi im a techy, my friend brought a laptop to me with this and she was running IE7 and after removing truck loads of malware i still couldnt get IE to open so i could download some software, i remembered vista came with a no addons option for IE7

    So click start and type into the search Add-ons and click the IE logo it comes up with then you can click the balloon at the top and disable the kiwee toolbar addon

    Hope this helps
