to add once you do this you will need the mcafee uninstall tool from here:
http://download.mcafee.com/products/licensed/cust_support_patches/MCPR.exe
and webroot here:
http://support.webroot.com/cgi-bin/webroot.cfg/php/enduser/std_adp.php?p_faqid=1761
once done i suggest a minimum of ccleaner or better something like jv16 powertools to help clean the registry for anything left.
