Before we get the mainstream of replies comming in, I have one more suggestion which WILL show the startup shortcut
Go
HERE and download
Autoruns
After unzipping you will find the following files now: autoruns.chm autoruns.exe autorunsc.exe Eula.txt
Double click autoruns.exe.
If this is the first time you launch autoruns, you may be prompted to agree to the license terms. Either accept them and use autoruns or decline them and remove autoruns from your hard disk
Now when it starts, it will do this big scan for everything that starts with your computer.
Do NOT untick anything (even if you don't want it to start with Windows)
I only want you to look on the right hand side, all the way down the long list for:
c:/program files/common files/ microsoft shared/web folders/ibm00025.exe
Once you find this startup entry, untick the box, on the left hand side, corresponding to it.
Exit autoruns, and restart
Hopefully it's gone !!
Note: most of the files in Autoruns allow Windows to start, therefore do not disable anything but
ibm00025.exe (The little bugger it is !
Please reply back once done
