Is two different Antivirus in one PC causing problems????

[Sabi]

I have Antivir, Ad-Aware and two Firewalls in my PC.

Every time I turn my computer on, the AntiVir appears automatically for a second or two. It also comes up when there is a virus scanned through Ad-Aware, wanting to know the action for the infected files.

My question is: Can I install "Norton AntiVirus 2005" (which I got from my friend yesterday) [:">] without worrying to clash the two Anti viruses?

Furthermore I want to buy "Panda Antivirus" or "Zone Alarm" but I am worried for the same problem if all Anti viruses appear automatically together and cause chaos

Any advice please?
Thanks

Shame as P2P a good thing - just look at Skype

Agreed, but everything that can be abused will be abused
