Ok, I am the DH, whatever that means. (Designated hitter?)
First let me start by saying yeah, I am a systems programmer, but not in the Windows environment. However, I am sort of savy on this, as whith what I do, I seem to be on the front lines more that I would care to be when one of the little varmits gets loose.
Anyway, It sounds like you are running XP with service pack 2 installed. If this is the case, that would explain your scanner reporting this. What happens with with these scanners is they are so focused on what they are looking for that they often report false positives. For instance take the following hypothetical situation: You have antivirus software A installed, but a friend wants you to try antivirus scanner B. When you install B and run the scan it reports that you have several viruses. You didn't get this with your old software, so you wonder if it missed them. You run scanner A and it reports similar results where it didn't before. Whats going on! First DON"T PANIC! The virus scanners are seeing the virus signatures that the other virus scanner has in its library and vice-versa. You get the same type of thing with the anti adware/spyware/spamware/scamware software. In their defense, its not really their fault -- there are so many different products available that you can't know exactly how every one of them stores the database. Ususally they focus in on specific products that have a large share of the market.
I must say, I am surprised that this was reported in your case, because this one should be known as its part of the operating system (well, not really -- don't get me started bashing Micro$oft) and appears to be a valid file. If you are a little skeptical and think this may be a false positive, there should be a FAQ or an email support option on the software companies site that will either tell you its ok, or you can ask if its ok.
I will agree with you a little on the virus software statement though. Sometimes I think the frequent "non destructive" viruses are generated by guys that work at the antivirus companies to maintain sales and update contracts. However, there are those, like the SQL Slammer and MS Blast worms, that are so well thought out and well written that it is obvious that there are people who could make better use of their talents.
Hope this helps.
