I have a friend who used to be an insurance broker and more than 10 years ago decided to start selling computers for a living instead. That he is totally self taught, doesn't advertise and, to this day, makes a successful living from supplying and installing computers says a lot for his abilities. He recommends Panda as it deals not only with virus protection but also spyware and malware in one go. I must admit I was very tempted when I had my AVG problem - see below. However I am using Avast now and slowly getting used to it.
P.P.
