OzExpat, If you uninstalled those programs it should be safe to delete those leftover program folders/files that are still there. Just leave them in the Recycle Bin for a few days and if no problems appear get rid of them.
I've been doing some 'housecleaning' on my laptop, removing old unused programs, clean-up, defrag, etc. Now when I look at my 'Program Files' folder, I still see files for programs that were uninstalled (using 'Control Panel> Add & Remove Programs' option). Eg I used to have Norton AV, then McAfee, while I now use Trend Micro. I had long ago uninstalled both Norton and McAfee but the folders are still in the Programs File taking up space, a few MB each.
Question; Do I simply 'Delete' these folders or could that cause some problems. What is the best way of getting rid of these sort of folders once the program itself has been uninstalled ?
Thanks, in anticipation.
