Are there any antivirus software for free that are better than CA antivirus.?norton antivirus

u can use powerful antivirus such as kepersky or norton antivirus 2007 and panda titanium. this three top software provide powerful protection to your computer. but if u want the normal protection level u can use avg 7.5 or avast 4.7 home edition. but i think avast is better than avg 7.5 because the files database update more frequently than avg 7.5. so your computer get the latest antivirus protection from virus,spyware and adware. moreover this two software is freeware.

Try using AVG antivirus. It offers very good virus protection for free but you have to pay if you want firewall and anti-spyware services.

To compensate that, you can download ZoneAlarm firewall which is also free. Just like AVG, if you want the antivirus and spyware protection you have to pay for those services, but the firewall is free.

For spyware you can use SpywareBlaster. Unlike Spybot or AdAware, this program prevents spyware from being installed in your computer, no scans. For this free version you have to run the updater manually, but if you pay it will get automatic updates.
