For some reason my Mozilla's browser changed the start and search engine from Google to "mystartseach". I have verified in options and Google still appears to be the homepage. Then I deleted all search engine options but Google and Wikipedia. I specially selected and deleted "mystartseach" engine. Then I close the browser and restart it with no results at all. Definitely this is a virus that is controlling my Mozilla browser homepage. Please if someone knows what to do, I will appreciate it if you could help. Tks!
