I have Mcafee and Windows Defender running on Windows XP and I don't know when it happened, but all of the sudden, I could not launch IE. I ended up ftp-ing into the Mozilla site and getting that browser loaded on my machine, but even lately I have tried to download IE8 and nothing happens. It looks like the download did not take place and I can't launch it. I really don't want to wipe my machine out - so if anyone has any suggestions, that would be awesome! Again, Windows Defender and McAfee are not picking up anything here.
