No problem. Just remember viruses arent really a problem on macs, so just get one thats really lightweight. Ones that only deal with mac viruses are the best to get.
Is Microsoft Security Essentials + MalwareBytes Anti-Malware a good A/V solution? What about Norton 360 or Kaspersky? Whether i pay or not isn't a factor.
I would like an AV with a good UI and as high detection and real-time protection rates as possible.
