I took my netbook to a local computer place - they ran some scans and apparently installed your free product - and added it as a plug-in to FireFox (52.0?). I got it back and all my Firefox data is gone: all the open tabs, all the history, all the bookmarks. They claim they only ran 3 scans, and came up with one virus unrelated to Firefox. So how did SUPERAntiSpyware get in there, and how do I get my data back? Thanks.
