I have problems all the time with mCafee missing malware, very dangerous malware.
got mc afee as well but got a troyan horse now ( i guess... ) my screen is filled with errors and fake security windows (with avg logo's while i dont have avg xD) opening some porn site every 5 min... and making an awefull lot of noise.
now did a full scan with a fully updated version and nothing found. cant find the name of virus cause the virus affected .exe files so taskmanager.exe as well -.-
my faith in mc afee went to almost zero.
dropped to zero when i read that for help at some helpdesk i have to PAY.
i already payed for the anti virus assuming it would help protect my computer. now they failed and i cant even get free costumers support.
so id say no right choice xD
