AVG versus Norton?

[Spellbinder]

Can i have both AVG and Norton installed?

I'm trying to get my friend's computer totally free from everything.

I have run HiJackThis and fixed everything.

I have run Norton, but it says i have nothing.

Yet i found a backdoor.

AND a virus they have in their own database! But at least they had information on how to remove it. ( http://securityresponse.symantec.com/avcenter/venc/data/w32.sober.o@mm.html#removalinstructions )

I also found several spyware even when Spybot-Search&Destroy says i have none.

I run Adaware and found only cookies.

Now i have ZoneAlarm (works good so far)

Norton Symantec Antivirus (don't know if it works at all?)

HiJackThis.

Adaware.

Spybot-Search&Destroy.

Do i really need more software to polute the computer if i want to be sure to get rid of all virus and stuff?

Anyway back to topic, can i have both AVG and Norton installed?

you probably can.

but it might be a problem.

because they might interprete eachothers actions.

as being those of a virus.

but its really not necessary.

if you keep norton updated.

to have any other antivirus.
