I have to disagree on your last comment about being a complete waste of time. Though I do agree on the fact that detection on the reviews is more of unable to fully measure, not all youtube reviews force a decision/opinion.
If I am right, Plexx used biozfear on youtube or something like that and the few videos I watched, none gave a verdict. Instead he or she would let the viewer decide. I did enjoy his videos most though they were long. Video editing was not his speciality by the looks of it. Emsisoft Anti-Malware, Norton Antivirus and some others were examples. He or she also did recreate the Webroot journalism or rollback feature.
Unfortunately his or her videos seem private or gone as I cannot find them. Maybe I am wrong and Plexx is not the youtuber I am thinking.
