It's all prank ,but virus will not have so long name.

Type "best free anti-virus of 2014" into your search engine. You will be presented with a variety of choices and lists by those who have reviewed the available free anti-viruses and how they are rated. Good websites to look for include 'bleeping computer', 'pc magazine' and 'cnet'. All of these will have what you are looking for. If you would like a personal recommendation, I would suggest you download 'bitdefender' or 'panda'. Avg Free Safe is a suitable anti-virus but be sure to download it from AVG itself and not through any third party. Also, there is a website named 'mostiwant' and they have recommended free computer security downloads with direct download links. Try there first and look for the free 6 month trial of Norton and install that as Norton is in the top 3 best anti-virus category. That's the one I use.

You probably have an unwanted pop-up cooky, which Bit Defender does not block. I suggest you download Free Spybot Search and Destroy from http://www.safer-networking.org/dl/

Quickly and completely remove Knctr from your computer by downloading "Should I Remove It?", its 100% FREE
This will remove Knctr from your computer.

Or, you can uninstall Knctr from your computer by using the Add/Remove Program feature in the Window's Control Panel.

  1. On the Start menu (for Windows 8, right-click the screen's bottom-left corner), click Control Panel, and then, underPrograms, do one of the following:
    • Windows Vista/7/8: Click Uninstall a Program.
    • Windows XP: Click Add or Remove Programs.
  2. When you find the program Knctr, click it, and then do one of the following:
    • Windows Vista/7/8: Click Uninstall.
    • Windows XP: Click the Remove or Change/Remove tab (to the right of the program).
  3. Follow the prompts. A progress bar shows you how long it will take to remove Knctr.
  4. If for some reason uninstallation fails, please install Microsoft's uninstall fixer utility which will help fix problems with programs that can't be uninstalled at support.microsoft.com.

Hopefully it works and solve your problem. Please rate, thank you. Sharing is caring. :)

There is no way to fix this outside of safe mode. If it is that serious, then you have to get into safe mode or reset the entire software.
