uninstall mcafee
Of recent, I would not recommend McAfee as I found that when you try to uninstall it from your system, sometimes it does not uninstall cleanly.
I found this out when I tried using one of the programs that uses vbscripting to do certain things and causing errors where it would intercept vbscript engine calls, and cause error because it redirected most vbscript calls to its dll. Which is good, if it was installed, but when uninstalled, it didn't clean up its changes and caused problems.
