I've recently ditched windows 7 for Ubuntu 11.10 64bit... I'm a total novice and was wondering do I need to make any changes to the firewall?. I read somewhere that the built in firewall doesn't need touching...but a friend says he uses firestarter,I'd be really grateful if someone could advise me weather to just leave well alone or if I should make certain changes,I'll be doing a lot of web browsing and also proberly a bit of online banking to. Infact this is one of the reasons I've switched to Linux as I was told its much more secure than windows... I just want my comp to be setup in a way that I can access my bank account safely and not knowing what to do about the firewall or how to configure it is off putting... Also do I need an antivirus?..I know bitdefender and eset do a free Linux scanner but again I've heard there not really needed. Thanks in advance to anyone who can answer my questions...much appreciated. Dave...
