I consider myself be reasonably responsible about protecting myself against nasties. I have a hardware firewall and a fully paid up subscription to Norton Security. I don't download suspicious software and I have my IE seurity options set at an appropriate level yet I still found myself being infected by something which caused my browsing activities to grind almost to a halt. Adaware eventually sorted me out after some advice from E Liam on another thread. Unfortunately we are paying the price of Microsoft's success with dominating the market place. Is it not the case that those who have moved onto Apples or use Lynux etc are much less likely to suffer from these mass attacks on our computers?
