Could you please tell me if Avast 4 Has a spam guard and or a fire wall. If not is it compatible with them?
Thank for your help and a great product.

I am not sure about avast. But try Spambully. It is amazing and it learns each time you receive a spam mail . One of the best I have come across.

dgkiwi,
Avast is an antivirus program only. However, it can check email for viruses and it’s the best one I’ve ever tried for this. ;D
Therefore, you will need a firewall and a spam checker also. I use eTrust EZ Firewall 3.7.211 (free for 1 year) and SpamPal 1.53 (freeware). 
I know that you’ll probably get more suggestions for firewalls and spam checkers. But, I’ve used quite a few of the free ones and have settled for the ones I recommend. 
For free firewall, sygate or zonealarm are very good, this site has a freeware section with loads of other stuff including antispam:
Its got top 20/100 downloads and how popular/good things are etc.
Avast is there and comes out tops.
You can check here at Ad-aware and Trojans Tools and Firewall & System tests sections…
To be short, I use Spamihilator (Culpeper uses Spampal ;D) and ZoneAlarm free.
