The simple answer to your question is NO.

And here is why, your firewall will give you some protection against unauthorised entry into your PC but viruses usually don't try to get into your PC by brute force. They tend to either piggy back on authorised downloads, are embedded in with other software or are disguised as an application or utility.

Now, once pass your firewall "your PC's goose will probably be cooked".

That is why you need, as part of your protective arsenal, anti-virus and anti-spyware software, a firewall is just not enough.
