My uncle is the family computer expert and I asked him about this AVG virus software someone recommended to me. His reply was to not come to him when I got a virus. I went with Symantec Endpoint Protection like he suggested. I don't know if one is better than the other, but I like having someone around who can help me with computer problems.
No offence to your uncle but using Symantec on a stand alone Desktop is a bad idea, especially on older systems. The resource footprint of Symantec is HUGE. It can be done in a corporate environment because it uses a Server-client model allowing most of the resource intensive work to be offloaded to the server (Updates, Active Scanning, Email Scanning). In a home environment this all has to be done by a single system and the slow down is not worth it
