I have just noticed 2 icons on my system tray/task bar in the bottom right of my screen (next to the clock). One is a shield shape with a red clock and the other is a yellow triangle with an exclemation mark. A bubble keepes popping up saying i have trojans and spyware but when i click on the bubbles it just takes me to different websites asking me to download their virus protection software. How do i get rid of this as it is making my computer go very slow and its very annoying. Any help would be appreciated. Many Thanks!
