Why is it a bad idea to have 2 firewalls installed on a computer?

Its actually better for your Computer's Security when there are more than one firewall but both of them should be one vendor. If these are two different vendors you should only have one and not two. This is because each vendor will configure their firewalls separately which will create confusion among the firewalls, the reason why you got the message from AOL.\n\nNow as you have both the AOL and Microsoft its better that you uninstall AOL and continue with Microsoft as you will be definitely having one of Microsoft's Operating System and remember to update your Firewall Firmware (Software) often, so that there will not be Intrusions to your PC from outside.\n\nHope you now got the idea\n\nBYE

for one if your using a windows pc the firewall supplied is junk. i could hack tht with my dog at the keyboard. get you self a better reputed fire wall like one by symantics. or which ever one you choose. install it an then it should ask you everytime you accses a program tht connect via internet. if you know the program is safe enable it to accese. if you are worried it is nopt then dont let it use the net.

Firewalls are set up at the workplace to stop people from using the computer for their own use.  I would go spare if I found out my employees where not getting on with their work and using my equipment to surf such sites.  Employers have to safeguard themselves from Viruses, ad-ware, and spy-ware to protect their customers privacy and data. Also you have to remember that an administrator can track exactly what you are doing on the computer. It is not worth your job. If you get caught and get the sack it will be on your work record.  Who will give you a job then? Nobody.

A firewall is a protection system for your computer that protects it from unsolicited communication when you are on a network.\nIf you use a good firewall then it will not only suspicious incoming traffic in the form of viruses,trojans,worms,spyware etc but also outgoing traffic.\nWhen you already have some virus in your computer and the virus wants to spread itself using  your internet connection then a firewall will prevent even that.\nThese days its a must to use a firewall as virus activity is growing.also use the Y! toolbar's spyware removal tool.It is very good for removing spayware that are not caught by your firewall.

Personally I think that people talk bad about it because it is  not free, it takes too long for a full system scan and it takes up too much system resources (during the scan) and hackers hate the firewall.  This is what I have found to be true.  I would prefer it too take longer and be thorough because it is better to be safe than sorry!

If you have the Windows XP firewall, then you've already gotten the answer.  But in my opinion, if you have a hardware router, get rid of the software firewall.  If you don't open any ports you're better protected than with a software firewall and no memory is used.  Why waste ram if you don't need to.\n\nDon't listen to the other opinions.  Computers are my job.  IF (and only IF) you have a router, get rid of the firewall.

They all are - a misconfigured firewall is as much use as a fart in a hurricane.\n\nHowever, to answer the question, a firewall is not technically a privacy risk as it protects your privacy.

this can be due to some firewall

more than one anti-virus will cause system errors and conflicts.... don't do it!!!!!

Anti virus is not a firewall. It could protect you from viruses, but not hackers. XPSP2 has a built in firewall that should be enabled, but I think it is better to go with Zone Alarm which you can get for free at http://www.zonelabs.com

You should only install one because there would be a conflict between the two I would suggest buying Norton Antivirus the Works!

Because they have free spirits. Firewalls block everything except allowed ports. And if an administrator does not allow a port for Skype or for Yahoo! Voice you will trick him. \n\nIt is just fair to restrict heavy downloads but leave the messengers alone - only there are admins who don't know how or are lazy to configure a firewall so that will allow more harmless services. \n\nThey use the "next" way of installing software and don't go into details.

maybe you shouldn't open it if its blocked?\neither disable the firewall or delete it.

Well..i have used Norton Products..and once installed it does not even allows Microsoft's Firewall & stuff to be used..\n\nAnd Mcafee, an rival of Norton... wont be allowed at any cost to run in tandem!

It's not advisable to run 2 anti-virus's on the same computer. You're asking for problems right away when you do that. Sound slike your McAfee firewall settings are to high since the site you are trying to get to sounds like a banking site right? In McAfee there's a Privacy Service program that goes along with it depending upon the version. Try disabling the privacy service along with lowering your firewall settings.\nFrom BeachBum-Desktop Support Technician

Dont install 2 firewalls or antiviruses at the same time as this causes collisions between them and therefore causes your system to crash. Only have 1 antivirus , 1 firewall and 1 antispy . Dont use Norton , use AVG . AVG is free and does a much better job then norton .
