Personal Antivirus pop-up

It appears that I am having the same problem as others. When I logged in this morning, a window popped up "Personal Antivirus" claiming that my machine is infected with viruses, worms, trojans, etc. I immediately ran a full scan on McAfee which reported no problems of any kind. However, I can't get rid of the Personal Antivirus popup and messages keep showing from bottom bar ... "Security Violation Error", "Windows Meta File Vulnerability-Vulnerability",
"Critical System Warning--Trojan Win-32.Agent.azsy", etc. I'm afraid to go online or do any type of work in Windows. My factory-ordered Dell is only 6 months old so I believe I have up to date programs. I use Mozilla Firefox and Vista. I am a consistent user of the internet, but have no savvy with equipment. Can you help me? Linda
