Avast home 4.0

I use Avast and zone alarm pro on several computers with windows xp Home and on my desktops I don’t have any problems with it. I installed it on my new laptop and am having problems with it. I am using the same versions. The two problems I am having on my laptop is web pages downloading very slowly and I can’t download anything. I have exact same software on all computers. I do get the message when installing about the conflict with ZA and did shut down the one component. I have checked the FAQs and tried them and it doesn’t change anything.
Any help would be greatly appreciated. I love Avast because after getting disgusted with Norton’s and McAfee’s I installed Avast and it found several viruses that the others didn’t and I was able to get rid of them. I really want to use it on my laptop. If I can’t get it to work on my laptop, I may have to look for a different software.

Thank you,

Ok, both programs could conflict in some systems. You get the message and then? What did you do?
Did you continue installing avast? Only the privacy options of ZA Pro could bring trouble with avast…
