Trusted Net is selling three AV products that are virtually the same, TotalAV, PCProtect and ScanGuard. The first one is being heavily advertised with pre-rolls and banners on YouTube right now and I've just seen a moderately big channel take a sponsorship as well. But they don't appear legit. I do IT security and have never heard of them, but that doesn't mean that they can't just be sublicensing a good AV engine with their own UI and extra features. But no. They appear to be barely above scareware.
First red flag is the 30 minuted count-down on the offer in your video description. That is a (kinda ridiculous) scare tactic no legitimate AV vendor should use, since AV is all about trust.
They also have an affiliate program promising up to 70€ per user convinced. That is unrealistic and will no doubt lead to fake reviews and underhanded marketing by those affiliates. This appears to be why they have good ratings on some, terrible ratings on other sites.
Third red flag are the many, recent complains about them on the US Better Business Bureau website. Malwarebytes, which is reputable, rates it as "potentially unwanted program", same as all the dubious system optimization programs that will tell you that there are 85 fixable issues but will only disclose them after payment. Some people have been saying that it's an outright scam, but I don't think that's quite true. Just almost.
It also just flat-out isn't very good.
