you dont have to purchase new software, but you really should update it. all antivirus software has an update feature. Try to update as often as possible, especially when you hear about a new virus.
You don't have to purchase new software, but you do have to purchase the subscription to get updates for your virus definitions. There are new viruses coming out every single day and it's not worth the money for software companies to give you lifetime updates. I prefer McAfee Internet Security Suite. We bought the 2005 edition, definitions are updatable for 1 year and this gives you firewall protection, antivirus protection, spyware protection, and a very good popup blocker.
sometimes you might have to pay for an annual subscription for updates. i have two computers and pay an annual fee to maintain the virus defs in my anti-virus software.
depends on the software. normally you have to buy one every year like mcafee. because they only do updates for one year then you need to buy the new one.
