Recent Bitdefender Users, I Have Questions

I refer to the paid versions of Bitdefender Anti-Virus.

1. What kind of impact does it have on the system performance? Is it light as the company claims? Is it prone to surges of high CPU usage that make it hard to use the computer till they subside?

2. Does it allow the user to disable "PUP" detection?

3. In the case of false positive detections, can you restore well from quarantine or is the targeted program gone, period?
