Correction: Norton and McAfee are the worst Antivirus programs for the PC!! They slow them down like a turtle and suck at detecting viruses and removing infections I wonder why all companies I've been at use this piece of crap
Norton HAS improved a lot in terms of system resources and being much lighter... But its antivirus components is still subpar compared to others... I run Kaspersky Internet Security......the king of Antivirus programs
