I had given my brother to use my pc for sometime. He installed many games in it. I think he had accidentally installed malware in my pc. On Firefox I can see a weird searchqu toolbar. I tried to remove it, but it is not working. The browser is also working really slow. I had important bookmarks in it. I tried exporting them, but the browser freezes. I want some help to remove this searchqu toolbar. I cannot even remove the browser as I will loose everything.
