Hi amarjeet28, and welcome to the forum.
Sorry to hear of your problems. MalwareBytes Anti-Malware (MBAM) is usually pretty good at cleaning these pests, but occasionally more is needed. Malware (and spyware) removal is no longer performed in this forum. You can get free expert help at SpywareHammer.com:
You will need to register there, and download a few tools. The instructions at that link are fairly straight forward, but you might want to print them out.
