What is the operating system and service pack on your laptop? Is it totally up to date with Windows Update, including any parts you may not use. For instance lots of people use another browser than Internet Explorer and neglect to keep it up to date, which is a mistake as many processes, including McAfee rely on it.
When installing McAfee make sure all entries in Control Panel > Programs > Uninstall a Programs pertaining to McAfee are uninstalled. (Add or Remove Programs in XP)
Do the same for AVG and run their removal tool from here: http://www.avg.com/ww-en/utilities
Run McAfee's removal tool (MCPR) which is linked under Useful Links at the top of this page or here: http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe
Run the McAfee Preinstall tool: http://download.mcafee.com/products/licensed/cust_support_patches/McPreInstall.e xe
Install your software from your online account, not from any CD you may have, https://home.mcafee.com/secure/protected/login.aspx?

A thousand thankyou:McAfee all access total protection 2012 installed !!
That's good, all the best ;-)
