VPN BITDEFENDER short free version causing damage to the cash

I used VPN BITDEFENDER short free version only twice; the damage was significant, it erased the log of all phone calls in my magic jack communications, which is important to me, it also erased the automatic log in of several accounts that I had to restore and waste my time again. This is about the damage that I noticed right now, I think over time there will be more problems. I can imagine what kind of damage can be caused by full paid version. Stay away from this "free option"
