The people who answers posts are volunteers. If anyone is "ganging up" it is because it is the slow season, we are bored, and there are not enough new questions happening.
I have never experienced any file deletion, and the number of similar complaints on this board can be counted on the fingers of one hand. If you really suspect something nefarious is going on, make backups of your tax data to the cloud, a flash drive, a non-rewritable CD, or print copies of your tax return so they can be read the light of a candle even if your computer dies in a Carrington event.
(I'm not joking. I have genealogy documents that I scanned in 1990 at the then-unheard of resolution of 300dpi, and I also took photos of them with B&W technical film. Those negatives contain far more information than the scans, don't need to be ported from computer to computer when disk drives and CD readers disappear, and can be viewed with a magnifying glass and a candle if all technology fails.)
