How to get rid of questscan search or questscan virus.


what is questscan ?

questscan is a search engine which hijack your browser and every time you search something on your browser it will searched on questscan.

My story

One day i m watching video on net and one video is not starting required some plugin for Firefox called divx. So i download the plugin from that video page called xvidsetup.exe that contain ad-ware and virus my  antivirus delete that file’s but to watch video i have to install  that plugin so i have decided to disable my antivirus protection and install plugin but its to late i get infected by it. After that when i enable my  antivirus protection its delete all infected files but plugin is still remained installed in Firefox and it change all the setting’s of search engine when i type anything in navigation bar for search it will automatically redirect to questscan search that is to much annoying . I try to disable that plugin and again try to search  but it again redirect me to questscan after every thing i got a solution.
