I'm not sure if it happens at a specific time or randomly.

The Panda scan just found one single cookie , did the rootkit scanners find anything?

And lets also try an Spysweeper scan , you can find a link and instructions for it in the "prework" link just below the link you used earlier for Ewido.

When done post the log from that please.

The rootkit scans didn't turn anything up, I don't think. I actually already have spysweeper on my computer, running every night. Hasn't found anything in a while. Everything really looks okay on my comp except for that taskbar "program" that appears every so often. It actually just appeared as I was typing this, and all I have open are 3 internet explorer browsers. If it makes any difference, it also will happen when the screen saver is on, and it will exit the screen saver as a result, going back to the main screen. It makes going into any type of powersave mode after I leave impossible.

Im thinking it might an app that is updating it self , do you have programs running with autoupdate enabled?

And have you also tried the Spysweeper scan i mentioned? You can also try an extra online AV scan from Kaspersky:

Post the log from it please.

here's the latest log.

Also nothing wrong in those to be found. We could try these online trojan scans to see if they find something:
