I am going to select my words very carefully as I don't want to start a unfriendly discussion here.
Just my opinions.
Even the worst anti virus,malware,adware program that is running is better than the best that's off or disabled.
Either of the two you mentioned will work and work for you if they are running. I use both
depending on where I am going on the net.
I have no idea why a person will turn their program off when on-line.
I have no idea why people will open a downloaded file before scanning it.
I have no idea why there is a rash of malware trojans,virus and other junk being reported if the programs are running.
I do know there is little or no mention as to the site where they got the infection from.
Well I better get of my soapbox before I fall off...LOL
I am happy to see there are people here that know what programs people need to clean up
