The real question is what updates are they talking about?
My Avast setup:
Enabled
------------------------
File System Shield;
Mail Shield;
Behavior Shield;
Script Shield.
Disabled
---------------------
Cloud;
Web Shield;
P2P Shield;
IM Shield;
Network Shield.
This is not my suggestion, just my resolve.
The ONLY thing I want updated, on a regular basis, are the Virus Definitions, which I do manually.
I also use Ad Aware, since their beginning. Originally a ground breaking program.
Also Malwarebytes.
And a few others occasionally!
I think many people are quite anal about virus protection. And no, in my history, since the general public was first given access to the Internet, I've never had any kind of serious outbreak. A few things here and there, but I've always simply removed them. Before the Internet I also had a few, given to me via floppies, again they were no big deal.
IMHO, all one needs are good hardware "AND" software firewalls, monitoring both incoming and outgoing traffic, running in stealth mode, and a good anti-virus program. No, not one with all kinds of bells and whistles, just a plain vanilla, REALLY STRONG, antivirus program! And that's it!
