One hour ago, my computer popped up with several msgs relating to being infected. I have McAfee protection but it was the "Antivirus Live" that popped up to say my computer is being threatened. The threats mentioned were BankerFox.A and win32/nuqel.e
Went on to say the files "wgatray.exe" and "wuauclt.exe" were infected.
When trying to activate McAfee, I can't.
Also, a "Spyware Alert" notice came up too. And even finally some "porno ad".
I shut that computer down. Am writing from another computer.
Please advise but take step by step.
