I guess my take on things is kind of like the physician's creed - "First, do no harm." To extend this analogy a bit, the first thing any physician will do is assess the situation and only take steps necessary to stabilize the situation and prevent further harm to the patient. In this case, from what we know, the "patient" has a problem which is annoying but not life threatening. Recommending immediate "surgery" on the registry is not something I would offer right off the bat.
The next step is to gather information in order to make an informed diagnosis. From that standpoint, I think Journeyman's advice was a step in the right direction. Running antivirus and spyware checkers is usually good advice, in that they not only gather information, but may also correct the problem by themselves. The advice I offered also would do no harm and would help to gather information. Asking other questions about the problem also can save time in the long run and help to better diagnose the problem.
Once the information has been collected, only then should a diagnosis be attempted, and corrective actions recommended. In my opinion, even then one should start with the least radical or easiest to perform and reverse if necessary. And generally speaking, it's best to take a little more time to consider your advice before you post. And if there is a precaution involved, like backing up the registry for example, try to always put that information first instead of last. Being first to post is not nearly as important in trying to help someone as being correct.
Finally, the "doctor" needs to bear in mind her/his own limitations. If you're uncertain, say so. There is no shame in not knowing something. None of us is omniscient. Well, maybe Jafo, Yrag, IPlural, and a few others depending on the subject. P As an example, I normally don't post at all on hardware/tech type questions because I know there are others here who know far more and can better help the person. That's what community is about, balancing each other's strengths and weaknesses.
Anyway, sorry to hijack the post a bit, but these things have been on my mind for a while, it's late, and I'm bored. I'll shut up now.
