As well as my C drive, I also have a D drive, where I park unused programs e.g. X-plane which occupied about 27GB. I normally just zap those programs which I decide are not only unused but are now obsolete. But this time round I decided to BC wipe as well x-plane ( I have a newer version ). Then I discovered that BC wipe each time I start the PC pops up on the desktop to announce it is still wiping in a directory called RECYCLER. Looking into the D Dir list, I find I have another directory called Recycled.... which contains two zero size sub dirs S-1-5-21-1801674531-1960408961-839522115-1003 S-1-5-21-854245398-776561741-839522115-1003 That they are empty is not true because BC wipe informs as it goes along on the actual operation and I am seeing xplane files names as the current wipe targets. Also when I run Treesize on the C: HD, It tells me that all the directories have an owner called S-1-5-21-1801674531-1960408961-839522115-1003. All except two:- Windows and another directory I had never noticed before called a3b863c2e230523d9a596870. This contains two subdirectories called AMD64 and i386 Have I got a virus? Can anyone clarify? Thanks Fred
