I think this is still valid....: https://www.wilderssecurity.com/thre...n-free-and-paid-bitdefender-antivirus.338665/
So it is cloud based only and has no option to set exclusions and auto delets files. perfeect for installing on clients' computers does it being cloud based mean that it is any less in protection than the actual Bitdefenender AV?
I found that BitDefender Free would not become active if the Control Panel Internet Explorer security settings for the Internet Zone were set to HIGH. I run Windows XP and this is one of my ploys to toughen XP against exploits. I guess that BitDefender Free uses the Internet Explorer API, otherwise why would setting Internet Explorer security to HIGH cause a problem for BitDefender. That begs the question, why does a supposedly reputable antimalware firm do this? The other question is do the paid-for BitDefender AV products also do this. Agnitum, AVG and Avast, for example, behave properly when Internet Explorer security is HIGH so they obviously author their own code, presumably to ensure quality and security to prevent malware from disabling it.
