Spyware/Firewall advice needed

I just got an email from a friend, saying her computer runs slow because she has a TON of virus & firewalls running. Here's the list of what she has installed, I would really appreciate if someone could tell me what she does NOT need.

Norton Security
AVG 7.5
McAfee
ZoneAlarm
Spyware Doctor
Ad-Watch 2007
Ad-Aware 2007

Thanks in advance for any and all help.

 

last time i checked Mcafee and Norton and few others do not go along with each other and will slow down or will become null (each cancelling each other).

tell your friend to use
mcafee or norton or AVG or zonealarm
adaware and adwatch

 

Uninstall all and try Pandasoftware.com evaluation copy then scan.

 

I would suggest Panda Antivirus, as kaung said they don't get along

 

Exactly Don. I am also using same software for last 4 years and don't have any issue

Moreover you can also try Avast

 

use avira as the anitivurs and for spyware [ i really dont know]

 

To everyone that posted, I really appreciate your help. She ended up removing everything except AVG and ZA, but also liked the features that Panda offers, so she'll probably give it a try tomorrow.

THANKS EVERYONE! ​

 

If you want the best you should give a try also to kaspersky !

 

People need only 1 antivrus and 1 spyware remover IMO or maybe 2 spyware removers
but def 1 antivirus software

 

i would suggest kaspersky and Zonealarm

 

I always suggest people to get Kaspersky and BitDefender. You don't need anything else.
