I had their Registry Cleaner on my laptop and used it a few times. The reports claimed to have corrected the errors it identified. Not sure that they existed, but that is not the issue... A pop-up window appeared offering an update, which I accepted. The "update" removed the entire program from the computer and terminated. The only things remaining are two folders; one containing the notepad text of the action and the other, an empty folder that formerly contained the program. So much for the update. I'll not purchase from Uniblue again. Buy at your own risk. read full review »
