The most important part is to get rid of whatever carried that 'crap' onto your PC - source vs symptoms.

Usually the malicious programs that promote Bing Search are installed alongside a freeware software (video recording/streaming, download-managers or PDF creators) that had bundled into their installation this browser hijacker. This browser hijacker is also bundled within the custom installer on many download sites (examples: CNET, Brothersoft or Softonic), so if you have downloaded a software from these websites, chances are that the Bing was installed during the software setup process. Very often users have no idea where did it come from, so it’s not surprising at all that most of them assume that Bing Search is a virus.

Get rid of anything in the Control Panel > Programs & Features that you don't specifically remember installing yourself.

See this Google search for other articles about removing that garbage.

I've checked that already. There is no unwanted software installed. As I already said that I've tried Malwarebytes, Hitman Pro etc but didn't find anything and its not the https://www.bing.com/. Its http://bing.vc/?r=15443&lnk=ext2 .

Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac:<Command>)<Shift> A)

In the Add-ons Manager, on the left, select Extensions. Remove Bing Anything. Now do the same in the computers Programs Folder.

Windows: Start > Control Panel > Uninstall Programs. Mac: Open the "Applications" folder. Linux: Check your user manual.
