Lost data

My husband’s friend installed Microsoft Office 2007 on my HP desktop and cleaned up my hard drive. Now I can’t find my old data files, specifically last year’s TaxCut data. The software is there but I can’t find the data. I’ve tried everything I know, which isn’t much, but can’t find it. I’ve heard no files are ever completely gone unless your hard drive is reformated. Any idea how to find my tax info?

It depends on how the hard drive was “cleaned up”. You can try something like Recuva, http://www.piriform.com/recuva. Do you happen to know the file name/s of your missing data? If so, just try a search to see if they are indeed still on your hard drive somewhere.
