uhg...IMHO, AVG is a resource hog and will slow down many home systems, especially older computers that don't have a lot of RAM. I like Avast! better.

Okay, so you’re saying ZoneAlarm is fine…everyone is free to pick their poison. My preference for older and low-end units is Kaspersky. The problem with the many types of security apps becomes how much effort and user interaction some are willing to be involved with.
Just keep in mind, most people having these types of problems are operating on marginal conditions; further, newer hardware does not have similar or noticeable limitations and the stuff has become very affordable.
