All these programs are excellent (ie without fault)
But to have these "Live Protecting" programs all starting with Windows (including your ZoneAlarm) is in my opinion overkill
Regarding AVG
Let it be known to you and all others reading
AVG has lost the plot !
It corrupts under Virus infection (on many seen cases here at TechSpot) Very similar to the horrible Norton
It runs multiple things at startup - really slowing a user's computer down
And it never finds as many issues as Avira does
Now I was all for AVG7 a year (or so) ago. But AVG8 (in my opinion) is next to useless
Many (most) support uses, across the net, state you must have running:
1 Antivirus
2 Spyware monitoring Programs (please note: you have 4)
1 Firewall
Here's what I say (presently, ie it changes when programs change, etc)
Avira Antivirus
Malwarebytes (that's right no live protection on this)
Comodo Firewall
And that's it !
If you get infected (ie it happens)
Then install the multitudes of Malware removal programs
I also suggest to run Malwarebytes (updated) at least once a week (along with CCleaner)
Whats happened to everyone? You get a fast computer, and it runs like a Pentium 3 (PIII)
