the last two laptops i bought had McAfee on it and when i deleted it and put AVG, i've had problems getting Internet Explorer to work. I found out just using Add/Remove does not get rid of McAfee, here's what i did
McAfee Cleanup
a. Right-click on the following link and SAVE the download to your desktop,
do not select the RUN option:
http://download.mcafee.com/products/...tches/MCPR.exe
b. once downloaded select Run and then you can delete after it's run
this will remove anything left of McAfee
