Almost since i've got this computer about a year ago when you right click the desktop, or on an icon for example and the tab comes down after about 10-20 sec. I thought maybe it was just the computer, but now when I right click a Symantic AntiVirus instalation opens, i've all ready had the program since I got the computer. When i wait to just let it install it tells me to insert the install disk, but im not even sure I have it anymore, so i just click cancle every time it comes up. Is there a way I can stop this, I tryed to delete the program but theres an error. I have a pic attached.
