And web browsers, really, are the problem. Redirecting a browser to a bad site increases the chance of getting a virus.

One of the virus actions on windows is to modify hosts - I don't think that's possible on linux but I worry that browsers can be redirected by other means - eg a bad extension in FF.

That is, in fact, one failing in the repository (I think!): that although (eg) FF is packaged and (presumably) validated before offered via the repository, extensions and plug-ins are not. Admittedly a major task but it would be more reassuring.
