I can't say I am impressed by BitDefender; I tried the 30-day evaluation and so far as I can see, there is little opportunity to determine what should happen when a "suspect" file is detected and I can see no report on the actions taken by the software. I am sure that it is all there, just not obvious.
I think that like the Russian Kaspersky, I will forget the Romanian BitDefender.
It's has a quarantine section in settings, you can delete /remove infected files, review here https://www.tomsguide.com/uk/us/bitdefender-antivirus-free,review-3523.html .
Bottom Line
Simple and straightforward, Bitdefender's Antivirus Free Edition may be minimalist but it provides better protection than many paid security programs. Its only real competition is Kaspersky Free Antivirus, which has a quick scan and scan scheduling, but a heavier performance impact during scans.. As good as its defenses are, Bitdefender Antivirus Free Edition won't bog down your system.
