Something I did while attempting a programming lesson caused XP to display a window telling me that an error required vb to close and asked me if I wanted to report the error. I clicked yes and got a thank you window with a place to click for "more info". I clicked it and was given the url of an MS Webpage
When I got to the webpage I clicked "Download" and it downloaded a 72.2mb file called Vs6sp6B.exe. After the download was finished it went to another page which contained the message, "People who downloaded the VB Service Pack also downloaded..." followed by 4 other files.
I don't know whether anything in the SP will keep me from from getting caught in my program, but I figure if you use VB6 and aren't aware of the SP I would give you a heads up
