BitDefender is sensitize. It was preventing me from modding Fallout New Vegas yesterday and not allowing me to save keyboard layout changes within the game. I see people having problems all the time in forums like this and I bet they have BitDefender. Most of them are going to extremes to fix the problem when all it takes is a click on a toggle button in BitDefender.
I don't know much about .xml. I have opened them before and it looks like a spreadsheet to me. I had ransomware once when it was less mainstream and I had to waste many hours of my time to get rid of it. It was NOT FUN...lol. Avast antivirus and HitManPro helped a lot. I was lucky to have the weakest of three variants.
