I'm sorry but I'm not sure what "remove duplicate" functionality are you missing. Do you mean the remove duplicate files feature, formerly available in the AVG PC TuneUp product?
If so, I have bad news for you. The new PC TuneUp product is not able to find and remove duplicate files anymore. It has the Space explorer feature, which identifies large folders for you and you can do a manual cleanup, but the functionality is different. We received many complaints on the remove duplicate feature from customers who managed to delete not only the duplicate files but also the "originals". It is generally safer to not include this feature with AVG PC TuneUp.
If you need the "remove duplicate" functionality, you can search for third party tools. Searching for "duplicate file finder" should provide you with several results.
Hope this helps.
I have had AVG products on all of my computers for many years, however, the 2012 utility version is worse than the previous ones. Previously there was a REMOVE DUPLICATE selection and when I bought the newer AVG product the DUPLICATE capability is no longer available.
After sending e-mails to Customer Service, and making several phone calls to verify the lack of the capability, I was transferred to a "technician" who would help me with the problem. I was placed on hold for over an houe on 3 seperate calls that I made and never did talk to a Technician.
I am letting ALL OF MY AVG products just expire and had to pay for a seperate utility to be able to remove duplictes.
