Avast Antivirus Free Edition is lightweight. I recommend it. Usually, payware AV are bloated and restrict you. Norton is by the worse. McAfee is good in protection, but also bloated.
I would go with Avast over AVG. Both are very good.
But overall. I recommend a linux distribution. No AV needed. Pure speed!
