Hi, Check-out this extract from another forum (digital spy) I brows on the odd occasion. I stumbled on this just the other day as I was attemting to rid my own PC of Internet Optimizer. It worked for me ...
1. Look under Program Files; There should be a folder that calls 'Internet Optimizer'. In this folder there is a file that calls 'optimize.exe'.
2. Now go to your Task Manager, processes and de-activate (End Process) the process optimize.
3. Go back to the folder 'Internet Optimizer' and delete optimize.exe.
