EDIT: I got my answer to my question by following the advice given here and IMHO it may work but as I stated towords the bottom of this page it depends on your processor and the main reason What Do I really need another program running for unless I am stupid.....now is not the time to agree with that.....
Thanks for all the input

The question here is can you have 2 different antivirus programs installed and actively watching out for problems and not cause problems? The reason I ask this question quite a few years back that was a no no. Either install one or the other but not both at once. With so many programs to choose from and hearing that people are using more than, I have been wondering if it was ever true in the first place or are people having problems that they might not know about, as in conflicts between more than one.

when my mom got her a computer a few years ago (it was like a 166MHz cpu) that guy swore it was the right thing to do. I think he had put 3 different AV on there with no conflicts.

i've never tried it myself, i just use one (EZ-AV & Firewall).

I run f prot 32, and avg, along with zone alarm firewall and sygate firewall as well. I don't have any troubles.

Has anyone tried Norton AntiVirus and McAfee VirusScan together? I have tried it once in a Pentium II 400 and it was extremely slow. I had to format it afterwards.

I think a lot now depends on your spare CPU power , I have had Nod32 ,Bitdefender , Sygate and Zone all running together but I think it was a bit much for my machine , things would get pretty bogged down when exploring folders with lots of files.

No trouble with NOD32 and FPROT :)

Running FPROT, AVG, NIS & NAV. Running fine here.

See specs:

I have been running NAV 2004 Pro and NOD32 successfully for months now with no conflicys

Well from the responses it would seem that it all depends on the "horsepower" so to speak that you are pushing. Well as of now I am running F-Prot & Symantec on a 466 celeron with XP SP2 and slightly slow would be the meaning here, but what do you expect.

Thanks

F-Prot and nod32. Tweaked a few settings of course. ;)

What does NOD32 stand for??
thanks

No trouble with NOD32 and McAfee

have a nice day

While it might work, I would discourage it. AV programs are very effective at reducing the speed of disk access. Every file that is to be read or written needs to be scanned and have it's signature checked against thousands of known viruses.

I find that using NAV, there is a noticalbe lag when opening large files. F-Prot is better, but it still makes a noticable performance decrease.

I personally try avoid running AV programs all together for the above reasons. I'm careful enough not to run executable files from untrusted sources, and I run whatever I can using the "run as..." command, and selecting a user account with limited access. In cases where I download a file I'm not sure about, I manually scan it, rather than having real-time protection running non-stop. 99.999% of virus infections nowadays are due to novice users thinking it's a good idea to open "brittney nude!! (Real!11!).jpg.mpg.vbs.com.exe" email attachments.

ive tried it before with noron and mcafee, didn't work so, really really bad experince, .........couldhave just been my setup though?

really have no clue as to why any one would WANT to run 2 AV programs; I mean, if you feel your AV program isn't good enough to protect your machine, then use a different one...
And, as Zone said, the lag they put on your machines performance makes it silly to take the performance hit for no apparent reason...
Any of the programs listed in this thread do a fine job at protecting your machine....one is plenty!
