I also found the ‘Ok2’ popup on my desktop yesterday June 13 at 7a.m. it popped up during the night while I was not working.
Reading through this thread… in my Programs and features I have a new program that I ‘did not ask for’, same icon and installed three weeks ago, called “Update for Codec Pack” with the same Green icon that eficonnection posted for "“Update for Zip Opener”. It showed up while I was using Chrome a few weeks ago and innocently enough asked me to update the codec pack exactly when I was watching some video. Once I did that I had a new search bar show up by default on new tabs in Chrome. I removed it (can’t remember the name) and thought that was the end of it… not!

Uninstalling “Update for Codec Pack” brings up the same confirmation that eficonnection posted “Uninstall DSite update process?”, Clicking ok produced a ding and a message “Uninstall completed successfully”.

Post uninstall… I still have the following on my (Windows 7) system: c:\users<username>\AppData\Roaming\DSite folder. This folder has a folder called “UpdateProc” that has two files:

File 1:
Name: TTL.DAT
Association: Notepad
Content: the string “6014” (may or may not be related to the fact that today is June 14)

File 2:
Name: config.dat
Association: Notepad
Content: the string “1368002220|0U1V0T0MzutDtCtAyCtN0U1V0D0TzutBtDtCtAtDyDtByCtN0U1V0S0D0TzutN0P1C1F1Q0N1T1H1Pzu0C1F1Q1P1RtOtBtD0P1T1R1J”

Removed the two files and the two folders and will see after reboot.
