For some reason there random screenshots appear on my clipboard that I find while pasting things. What could this be? I've done a rootkit scan, and although there were a few items that came up, nothing seemed to be spyware. I also do have a few anti-malware, anti-spyware and anti-virus software installed and the sytem seems to be running decent. Windows XP with firefox. Recently I did have a drwatson error.
