When I click open or double click the icon on the desktop, nothing happens at all. I have this darn XP Antispyware that won't go away and keeps popping up saying I am infected, when in fact, it put things on my computer to tell me that I was infected. I have run S&D many times before, but it just won't open. I tried downloading the newer version and the same things happen. What do I need to do. Also, my computer stays on almost all the time connected to the internet, what can I download to set up a firewall so anyother computer needs to get permission.
If this is in the wrong spot, let me know. Sorry, I'm a newbie.
