Comparing Norton Antivirus with AVG I consider AVG more efficient in the detection of viruses. You can also try Microsoft Security Essentials.

I recommend you Microsoft Security Essentials. It is free, consumes low system resources and is efficient. You can download it from SNIP

You can try other antivirus software such as Comodo Antivirus, Microsoft Security Essentials or Panda Cloud antivirus. Comodo Internet security (antivirus + firewall) is a popular efficient security suite which can be combined with Malwarebytes to ensure the complete protection of the operating system.

My answer refers to current antivirus software. To efficiently protect your computer against viruses and other malware you need 1 antivirus + 1 firewall + 1 or more malware blocker. This combination is very efficient and is recommended to anyone: Microsoft Security Essentials + Comodo firewall + Malwarebytes.

In my opinion the following security software combination works very efficiently: Microsoft Security Essentials + Comodo firewall + Malwarebytes.

I recommend you to use Microsoft Security Essentials + Comodo firewall + Malwarebytes anti-malware. This combination is very efficient and free.

You can also install and use Malwarebytes Anti-malware with Norton antivirus. Malwarebytes is a powerful free malware blocker with high detection rates and scanning speed. [url]http://www.malwarebytes.org/[/url]
