my wallpaper was turned blue, windows security alerts popup, some saying "security breach beware! spyware infection was found", another one says "tracking software found, your pc activity is being monitored."
every time I try to open a program, such as firefox, the window opens saying "choose the program you want to use to open this file". also, I can't download new programs, when I try do start the set up it gives the same "choose program..." window.
If anyone can help or need more info let me know.
