There was a piece in the paper this week about anti-virus software. They recommended some of the lesser-known ones as being less cost and quite good. However, their point about the big-name ones was that, like MS-OS, they are so popular that people write stuff to get through them, whereas they don't bother with the lesser known ones.
I got a cheap one from PC World when buying my notebook, and it works fine. My son has a free one and he's not had any problems for years. HTH
