What's more annoying, is that you combat one annoyance (pop-up ads, programs installing behind your back, etc), and another one comes along:
I quite often (and they are increasing in number at a fair rate), get Microsoft Networking broadcast messages (advertising "pr0n" and "warez") showing on my screen on this 2000 box. I have no need to receive them at all, so disabling them completely would do the trick. Trouble is, I have no idea how to do this. I'm tempted to stop the Messenger service but am reluctant to do so in case it breaks something else. Might give it a try anyway... those messages are really starting to irritate me.
Sooner I get an AmigaOne and a decent web browser for it (even if I have to boot into Linux to use Mozilla), the better.
