During the past few days I have had an unwanted search / find box opening at random occasions when I´m browsing the internet. When the search box appears it refuses to close and scrolling is disabled. I´m also unable to type in the adress bar. It hijacks my keyboard and I´m unable to type anything in the adress bar. When this happens the only thing I can do to regain control of my computer is to restart it. I have deinstalled the browsers (Firefox and Opera) and reinstalled them again later. Ran Avast premium security and Malwarebytes. After running the antivirus and malware programs, a few issues were resolved, but still the issue persists though its now less frequent. I need to know how to resolve this issue completely as I find it very irritating.
