Save this as fixlist.txt, in the same location as FRST.exe
Run FRST and press Fix
On completion a log will be generated please post that
THEN
Download to your desktop process explorer from here http://technet.microsoft.com/en-gb/sysinternals/bb896653.aspx
Open process explorer and from the menu bar select View > Lower Pane
Select Explorer.exe
A Lower window will open
Then on the menu bar go to File > Save as…
Then select the desktop and click save
On the desktop will then be a text file called explorer please attach that
You may need to edit the file name from explorer.exe.txt to explorer.txt to allow it to be attached
Not quite right for process explorer
Could you run it again but ensure that you have explorer.exe highlighted and save the file as soon as you get an alert
