We've used PDF XChange for probably 15 years at work, it works well. The only thing I wish were better is the separate Tools program; I prefer the old one a lot more than the new one, so I always just install the outdated one alongside the new.
Is Malwarebytes still the best malware scanner around? Have not needed it for a while but I have a PS4 image I'd like to scan and not sure just MS defender is going to get it.
