,,,can anyone advise me on which firewall is easiest to set up? I have used Zonealarm, but recently my system has been invaded by zillions of trojans plus lovsan etc...nothing seems to work well!! I have had to use the restore partition facility on my HP three times in as many days to get rid of the invaders!! I have AVG running also - is the resident XP firewall any use?
Firewall is mainly to stop Hackers etc. from getting into your computer and compromising your data or stealling all your information therein or playing havoc with your PC's guts. It is not to designed to stop viruses. You need an anti=virus program for that. So you need both programs, but not more than one of each or you could build up conflicts. If you use a 3rd party firewall, before installing it, turn off your XP firewall first, then install 3rd party. Layer your protection.
Sorry about that - you're right. I was replying to the original post and sort of following on from huggyg71. As was pointed out, you need antivirus to stop trojans, not a firewall. I was suggesting that sorefingers may have accidentally left his disabled and that was the source of his problems, not the non-functioning firewall.
