I recently installed a Comcast version of McAffee and since I've been experiencing screen freezes, slow performance, etc. Opening & shutting down takes forever and in most cases when shutting down I receive the message that the system is not responding -- is this due to the security software or is it possible I have a virus? In some cases the CPU usage is showing as 100% (but not today)

McAfee and Norton are known resource hogs.
IMO I would unload McAfee (I did the same thing on a Toshiba Laptop for the same reason)and use Avast Free and Comodo Pro free firewall. If you need a real-time spyware prog, I have also been using Spyware Terminator, BUT, I don't install the toolbar that comes with it.
Your PC will not get bogged down as much as with McAfee.
The above are all free, there are also other Pay ones that will work fine too.

I noticed lately that Norton and McAfee are becoming free as many people have been dumping them for better AV's using less resources. The days of Norton and McAfee getting bundled in most new PC's is pretty well over with now....most people figured that they HAD to have them and they were the best. IMO, they are NOT the best....LOL

Some HELP in posting on Cnet plus free progs and instructions Glad to Help!

Hi XP - Thanks for the advice - Before changing over I need to uninstall McAffee, correct?

Just another comment: Playing videos has also become torturous within the Windows Media player - is the McAfee thing causing all of this?

Thanks,

Deb

Hi Deb,
Check the McAfee site and see if they have an uninstaller on there.
The media player thing could be spyware congestion. I would suggest running the free cleaners too.
