Re: need antivirus and firewall combo
My personal opinion is that NOD32 is the best, but there are other programs out there that are very good. Comodo Firewall Pro is a good one, besides having a firewall it can also scan for viruses and trojans.
Another option for a firewall is Zone Alarm free edition although it doesn't have as many features as Comodo. A good free antivirus to go along with Zone Alarm would be Avast, Avira or AVG.
Desktop: Dell Dimension E510, 2.5GB RAM, Intel P4 3.0GHZ, 250GB HDD, Windows Vista Premium. Might not be the best, but the old girl is still running good.
