Your McAfee software should have prevented any malicious changes from
occurring to your computer.

"Internet Explorer stops responding, stops working, or restarts"
http://support.microsoft.com/gp/pc_ie_intro

Since malicious software can be very hard to detect you typically need
to scan your system for malicious software with /several/ of the better
online scanners (Kaspersky, Eset, Trend Micro, Panda, Sophos, Symantec
etc.) If necessary, submit a HiJack This log to one of the expert web
sites that analyze these logs.

Issues with Internet Explorer can also be caused by the use of so-called
registry cleaners, which often damage a computer, sometimes irreparably.
If you were using a registry cleaner and it has an undo function, try
undoing the changes that may have caused your problems to occur.
