best internet security suite

hi guys i have had unsolvable problems with zone alarm internet security suite and i've had enough of it. can anyone recommend an internet security suite just as powerful as zone alarm or even better, most preferably with a multi-layer firewall and powerful antivirus. much thanks in advance

 

I use Sygate Firewall and Avast Anti-Virus. Both are very reliable and both are free.

 

thanx for the response. i meant full paid for all-in-one utilities such as kaspersky etc.
