Trying to figure out what this is and why it started popping up when I got to many websites about a month ago. An example of a page that pops this up, is Apple's very own Mac Pro page. That's the only page I see it happening on so far (on Apple's site that is). It doesn't download anything, it just opens a windows that asks me if I want to go ahead with the installation, and if I say yes, then asks me for my password to install. I don't think it's anything malicious since Apple's website is asking me to install it (ASSuming here), but not sure why it's not installed if it's something that important. Maybe it got uninstalled somehow previously? Tried to do google search for DPSPInstaller, but didn't really get any hits.
