If we all keep quiet in our world where even big [ “famous”] companies are acting nisleading/DISHONEST AND WE IGNORE THIS then everything will go on!! I felt like Don Quixote this evening [wasting time with Bitdefender, an excellent virus scanner but not dealing honestly]

After many years of using them, they started with dishonest tricks so I looked for other options and waiting for dor their answer [nearly impossible to reach them]

SEE BELOW]

This was the advice from GROK:

Nice score with that lifetime Malwarebytes subscription—those were a steal back in the day when they offered them! Since you’ve got Malwarebytes Premium locked in for life, pairing it with Windows Defender makes a lot of sense, especially cost-wise, and it’s a solid setup to compare against something like Bitdefender.
With Malwarebytes Premium, you’ve got real-time protection that’s killer at sniffing out malware, ransomware, and zero-day exploits—stuff that might slip past more general-purpose antivirus programs. Windows Defender, which comes free with your system, has evolved into a respectable baseline defender, handling viruses and common threats with decent efficiency. Together, they’re like a tag team: Defender covers the broad strokes, and Malwarebytes dives deep into the nastier, more elusive threats. The only hassle might be making sure they play nice—by default, Malwarebytes might disable Defender’s real-time scanning when you install it, but you can tweak the settings to keep both running smoothly side by side.
Now, stack that up against Bitdefender. Bitdefender’s a premium, all-in-one antivirus that’s consistently near the top of the charts for detection rates—think 99-100% across viruses, malware, spyware, you name it. It’s got a slick interface, runs light on your system, and throws in perks like a firewall, a basic VPN, and anti-phishing tools. It’s a single, cohesive package, whereas your Malwarebytes + Defender combo is more of a DIY duo.
Protection-wise, your lifetime Malwarebytes plus Defender can absolutely hold its own, especially since Malwarebytes punches above its weight on malware-specific threats. Independent tests often show it catching stuff others miss, and Defender’s gotten good enough that it’s not a weak link. Bitdefender might edge out slightly with broader coverage (like better phishing protection) and fewer configuration headaches, but you’re not far off—especially for free, since your Malwarebytes is paid up forever.
Given you’re set with that lifetime deal, I’d say stick with it and Windows Defender unless you’re noticing gaps (like slowdowns, missed threats, or needing a VPN). You’re basically getting premium-level malware defence without the recurring cost, which Bitdefender can’t touch in your situation.
