Is it better to install more then one Antivirus and Firewall?

I was thinking of intstalling about 3 antivirus to improve my protection. Will that be better then one.

NO! Only one anti-virus, and two firewalls but ONLY IF one of them is a hardware firewall and one a software firewall, in fact, that is recommended. If you want to scan your system for viruses using a second scanner, best to use one of the free online scanners.

Nope. I would suggest that you stick to just one.

They'll cancel out each other if you do.
nope, that's a really bad idea.

all that will happen is your system will grind to a halt as all three programs try to keep full control of the computer.

you only need, and should only run, ONE firewall and ONE antivirus program - anymore will simply cause problems.
Norton, McAfee and AVG(free) will not install if there are other antivirus software on the computer. When trying to install it will say you must un-install the ??? antivirus before you can continue installing this one. Now firewall should install both or 3...I have Zone Alarm and Black Ice and they work together...But I have tried using 2 antivirus and it says un-install other one before installing this one. Install can not continue...Thanks
NO! They will see each other as a virus, and probably shut down your computer. And the same for firewalls. They will try to get rid of each other. You won't increase your computer's protection, you will kill it.
That is the best way I know of to cause your hard drive to crash!!! Never ever use more than one ant-virus or firewall....their software will conflict and you won't get as good of protection.

Best thing to do is to choose the anti-virus that you really like...don't be the reason that your system crashes!!
NO do not !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

they'll kill the system !!! only one .

each will recognize the other as a virus !
you will not be better protected by having 3, you will have major conflicts

do not have more than one anti-virus or firewall
