hmpuhuphmhpmphumhpu I hate McAfee soooooo much.
Don't know if McAfee would cause a problem or not, but it has never done anything but cause me serious problems. I also see where a lot of people are having problems with USB dongles around the net. McAfee is easy to download and reinstall as long as you have all your subscription info. Uninstall it, then download one of the programs that removes the left overs from McAfee. McAfee's uninstaller ALWAYS leaves a lot of stuff behind, most of which can cause problems. If that works, download and install Microsoft Security Essentials
. I use it one all of my computers and it has always worked so much better than McAfee.
