I bought Bitdefender Antivirus Plus (BAP) again as I was completely satisfied with it in the previous years. Small snag, however, I had to uninstall the previous version. After installation, that went without a hitch, everything seemed to run as it should, without bothering me. Next snag, it blocked websites I used to use without problems because it did not trust the issued certificates. And there was no way to instruct BAP in the browser to allow to trust the previously trusted website. Websites like search engines like Duckduckgo and Google (gasp). Surely the most dangerous websites imaginable.
