*sigh*
ok very well, let's just wait and see... firstly we're assuming he mistyped his question, and secondly.. why would the popup address him to go to FixMS.net (an obviously bogus website)
Well, it's less of an assumption and more of an educated guess - given that his title specifically says "messenger service". as to why the popup would tell him to go to a bogus site, well, it's because that's what messenger spam does. It can't do anything else.
and lastly, why the hell would this happen in the first place if he DID have sufficient security on his system... unless he loves clicking ads..
All that's happening is he's getting popups. He could be using XPSP1, and messenger would then be enabled by default. Even WITH otherwise sufficient security, messenger popups will still happen because it's a normal part of windows. That is, untill you turn the service off.
spike, these factors are most important, in fact I'd put money on spyware.. sure it may use the mess service, and disabling it doesn't remove the problem, it just inhibits that certain function, (the broadcast)
As a person who's not gotten any significant problems in the last few years, and even wrote a sticky on making XP more secure, I think I know what's significant, and so there's really no need to be patronising (not that that makes me an expert - it shows that I'm at least competant). Actually, I think you'll find thhat disabling the messenger service DOES fix the problem of messenger spam. Disabling the service prevents both the broadcasting and recieving of net send alerts.
All I've done is offered the specific solution to the specific problem that was given. If he has a further problem after the solution is tried, then we can look at the more complex issue. However, there's no point making a mountain out of a molehill, untill you have proven first that it's really a mountain - that's just plain common sense.
Can we please leave it there now, because really, is this going anywhere? If he has a further problem, he'll come back and say as much. If he's solved it, he probably won't say so, because many don't (as nice as it would be for them to do so).
