My son sent me a video file that I could not open so I looked for a way to open it and came upon the Paretologic File Cure. They act like it is just a free download but when I did not buy it and tried to delete from my programs my e-mail, which I gave them...duh, became unusable. None of my emails will open. What a crock. They act like they will help but only ruin your computer. DO NOT USE THEIR PRODUCTS!!! The blankety blanks have ruined my email that all of my friends and colleagues have. They should be put on every message board to put them out of business!!!
