I have MCAfee installe (Came as part of Package) When I first used it It showed if a site was Safe Safeish or Dangerous. However when i started it up this morning when I search for sites it no longer Shows the ticks against the results ie Green Yellow or Red Is there anyway to rectify this My op is vista home premium.
Not sure what happens if it comes as a package.Normally you have to download the proper one for Firefox or Internet Explorer. Maybe press the refresh button and see if that helps. If still having problems you can always Download and use WOT.It does the same job as McAfee.
You can run both I Think.but maybe better turning the McAfee one off.I used to run AVG link scanner as well as McAfee and both worked but when looking in Task Manager there was a bit of a conflict between the two of them,So I would imagine it would be better just to run the one of them whichever one you prefer.I use WOT and am perfectly happy with it.I used to get the same problems with McAfee as you are getting.
