I have a computer running Windows XP home. I tried to install McAfee 2010 Anti-virus. I ran the disk and clicked on Install icon. It opens the first window but the window stays white. I tried it in the DVD rom drive and same thing. I tried another McAfee, same product, and got the same result. I looked to see if there were any other anti-virus products on the computer but did not find any. Any ideas?
