Bob, A virus can affect anything but I doubt that those areas would be specifically targeted. Your biggest risk probably lies with email these days.

If you haven't done so, get a good AV program and keep it up to date. If you haven't got one, there is a link from the page I gave in my first post here that will give you a free anti-virus scan if you want to see how you stand at the moment but that is no substitute for having good software on your computer.
