Win XP system, Foobar2000 and Boom problem

Inferior grade what?
The things I mentioned are obviously done via the browser yes, but that is about as bad as it gets. On XP you are forced to use old (and hence unsafe) browsers, which then run on an unmaintained networking stack and an unmaintained kernel. Anything unmaintained becomes more and more unsafe, when new vulnerabilities are discovered and not fixed.
