a firewall blocks virus traffic on a internet enabled pc.Also windows firewall is sort of bad because it only scans inboard internet so if you have a virus on already it can leave at will.

As a general rule of thumb, you should only have one anti-virus program and a firewall running at a single time. This will greatly reduce potential conflicts between similar programs that venture deep into the system kernel. Most free anti-spyware programs do not give you the option to enable real-time protection, but keeping them within the system as on-demand scanners is advisable.

Windows Firewall only offers inbound protection, that is, the filtering of information coming from the internet.
I suggest you read the Firewalls FAQ I wrote:

There is an elaborate answer to your question, as well as some general information every user should know.

thanks for the help on this

Dunno what ya'll say about it but I'm pretty satisfied with Hitman Pro for anti-virus and anti-spyware. This program is a bundle of several anti-virus and anti-spyware programs:
Eset NOD32 antivirus system (trial, expires in 30 days)
Webroot Spy Sweeper (trial, expires in 7 days)
PC tools Spyware doctor (demo, will not clean anything)
Lavasoft AdAware SE (freeware)
Safer Networking Spybot - Search & Destroy (freeware)
TrendMicro CWShredder (freeware)
JavaCool Software SpywareBlaster (freeware)
McAfee SuperDAT Virusscan (McAfee Primesupport license required, do NOT use when you're not a McAfee customer, since you do not have such a license using the scan is illegal)
Ewido Micro Scanner (freeware)
It automatically downloads the programs and their updates.
BTW: i don't know if it is available in any other language as Dutch (e.g. English)....

Robin

is it ok to have the antivirus running as well as a spyware scanner like AVG for E.G?

as at the moment it recomends not to close the spyware
but i havent got antivirus as yet??

thanks

It's OK to have both AV and antispyware running-- you do want to have a firewall as well...
They do different things-- but the firewall is your primary defense against everything. It's your security door. AV and AS remove stuff that sneaks past the Firewall. They help block as well... but the firewall is 1st.
