Alright, when opening the start menu on Vista 64bit, there’s a small picture in the top-right quadrant (the administrator icon), which you set manually upon first starting the computer, and subsequently at any point by clicking on it and opening the User Accounts window.
Now, a little while ago I noticed that the photo I had set as the icon disappeared, and was replaced by a circle with the four windows colors and a bright green check mark. This icon stayed for a while, then disappeared back in favor of the icon I had actually, manually set.
So has anyone seen this before, or have any idea what it might be? I have an antivirus and anti-spyware program running, but I’m still worried about a virus, hacking, or some other kind of incursion or risk that my lack of much tech-savvy makes me paranoid about.
